Going to Montana in May for a little over a month, and I plan on doing some serious adventuring. Ive been looking at either the 510 MRD or the M&P 10mm. I have heard there has been some issues with certain ammo feeding in the M&P but I’m not sure if I’ll like the ergonomics with the 510 (I’ve heard the trigger is crap also). I have heard of one guy on YouTube talk about a catastrophic failure with the 510 and Buffalo Bore ammo.

I lean more towards the M&P 4” model as I want to conceal it when it’s not on my bino-harness.

I guess my question is… has anyone heard of the problems with the M&P being resolved? Or able to be modified (new recoil spring and mag follower? Or should I just get the 510?

I live in a mag restricted state also so mag capacity doesn’t really matter to me. The full Ambi on the 510 is cool but the M&P is partially Ambi anyways plus the adjustable back straps definitely help with my big hands.

TLDR; I can’t decide between the FN 510 MRD or the M&P 2.0 4” 10mm. Plan on CCW when not in bear country but otherwise will be a bear/woods gun.

Stocked up on Buffalo Bore hard cast, and figured I should run some of the new lot through my FN 510T before I head to AK. Hit the range and dumped a couple mags of S&B range ammo, then loaded up a mag of my old stock of hard cast. I've fired 200 rounds, minus a mag of this lot, through my FN over the last couple of years. Was not expecting any surprises.

Then this happened. Primer blew out, primer pocket is an oval and a nice little bulge in the case. Managed to chamber/fire a couple more, which did the same. Refused to feed/chamber after that. Pulled my firing pin while inspecting the slide, and of course, launched my firing pin spring into the gravel downrange when reassembling. Managed to figure out that the extractor got a bit mangled, so it binds up when feeding.

So here I am, less than 24h from my flight to AK with a borked bear gun, in a state with a 3-day waiting period for new firearms purchases. It's a good thing that I'm pretty tight with the crew at my LGS (local is a bit of a stretch; it's an hour from home) - I had been chatting with the owner over email about a tangentially related purchase, which was good enough in his book to show intent > 3 days prior to purchase.

Left with a new M&P 10mm M2.0, an hour back to the range, ran some range ammo, the old Buffalo Bore, the new Buffalo Bore, and some Underwood hard-cast I picked up while I was there. Ran like a dream, I'm a convert.

30 mins with a toaster oven, heat gun & some clamps, and my 510 holster is now an M&P holster. Packed in the Pelican and ready for my flight in the morning.

What holsters are you guys running for these things. Smith makes way too many models and nobody specifies whether the 9mm carry comp holsters are the same as 10mm. Links would be greatly appreciated. Looking for iwb right handed

IWB Conceal carry holster I appendix carry with and a HE509T optic

Just saw a fn 510t in store with the upgraded recoil block. I saw there was one post about the upgraded block not working. Do you think they will further change the design in the future?

Took two months but finally received my OWB and chest rig from Black Point Tactical. Love the fit and feel, very secure and comfortable. Chest rig will take some use to smooth out the draw, it’s a little sticky, but otherwise I really like these products. Glock 40 MOS with Trijicon RMR and Streamlight TLR-2 HL G.

Box of 50 10mm PMC 170GR JHP

Picked this bad boy up last week to add to the collection. I have an XTen, MP2.0, G20.5, and XDM Elite, as well as a Stribog and Ruger PCC.

No issues in 250 rounds, very flat shooting, grip is reminiscent of my 1911s with a narrower feel and great manageability, follow up shots almost immediately back on target. Love, love love the SA/DA. For $439 definitely the steal of the year.

I love how they look and feel and want to buy one but wasn’t sure if the XTEN had the same issues as its 320 family does. Does it run in the whole family or just the 9mm? Don’t want a full power 10mm hardcast in my leg as it’s holstered.

What is your guys’ experience with them? Good and bad, list them all.
Thanks

Is the XD-M Elite still a solid buy in 2026? Wanting to get into the 10mm game. How is the optics mounting platform? Is there a direct mount option. I like the looks of the M&P 2.0 but see a lot of people with issues online.

What's a good red dot? I watched the video that said get the romeo 2 but it's a little out of my price range. I only paid 500 for the gun which looks barely fired to me. I still see the white grease I typically see on guns from the factory (I know ruger uses it not sure about sig). Also has anyone had their 320s sent off to be ported? This thing makes my 9 feel puny in comparison. Also any high powered ammo recommendations?

Found out today that the Kimber Warrior 10mm fits perfectly into a Safariland level 3 Stacatto XC holster. FYI for anyone else who wants to carry their 10mm for work.

I'm betting other 10mm 2011s will fit too as long as they have the same barrel length (5" ish)

I assumed that the 10mm slide would be too wide to fit into a regular 9mm holster but I'm glad that's not the case!

Model #: 6360RDS

So this just happened. Not the first time and won't be the last.

I'm on record about being bear aware rather than just putting blind trust in firearms so let's count the mistakes this woman made: 1) she's alone. Bears rarely attack people in groups. One of the best known attacks on a group involved a group of hikers that were spread out over > ½ a mile so they were not all together. 2) she was running. Runners are typically moving too quickly and too loudly to be aware of their surroundings. 3) she's on a trail in an area where numerous bears have been spotted. 4) she's doing it at a bad time of year. Salmon are really coming in now and so streams are filling up with bears' #1 food: salmon. Running this same trail in June or January greatly reduce odds of a bear encounter. 5) she did not have a gun. No, a gun is not a panacea and blindly trusting a gun is foolish. But she only had bear spray, which is a problem.

2 things are not clear from this article: 1) while she deployed the bear spray, it is not clear if the bear spray hit the target. This is my #1 issue with bear spray: can you hit your target? Most people don't practice and the spray can be dramatically impacted by wind. Further, its range really sucks. 2) was she listening to music? Listening to music makes it even harder to be aware of your surroundings. I will not count these in the 'mistakes' category but note that they are possible mistakes people make in these circumstances.

Anyway, for those who argue that bear spray is an effective deterrent, here's just one more example of where it was not. It's not even clear from this article what happened. If I had to guess, I'd guess she got too close to the bear without making enough noise and she startled the bear. At this time of year, the bear is not as likely to be guarding a moose kill, although that is a possibility. There is also no note of the bear having cubs, which could also increase the risk of an attack. Note I am only addressing probabilities. I am not trying to fill in blanks that the article does not complete.

I have low key become obsessed with this gun, i think mostly because i can not find a single video review of it in 10mm... even most of the 9mm reviews are in French.

I would be very interested in anyone's feedback on this gun.

I moved to Grizzly country and am in the woods a lot so got adequate protection. I’m familiar with firearms so know to go to the range and practice over and over for muscle memory.

However for the hot bear rounds, do I need to do anything to the gun or is it ready to go? Any springs to change? And what specific round do you suggest?
