Glock 40 vs SW M&P 2.0 Performance Center?

I'm in the market for a big ridiculous pistol. I've narrowed my search down to either of the two mentioned in my title. Does anyone have experience with both and a preference for either?

I understand the regular 2.0 has some reliability issues. I also think the ergonomics look a lot better on that pistol, so I'm kind of tied. Although I do think the long Glock 40 looks ridiculous, I also see some charm in it, so tough choice.

I am specifically looking to add a comped KKM barrel to the Glock, if I go that route, if that makes a difference.

As for my use case, there's no bears around me and I won't be carrying either. They'd just be for for swinging around at the range and with my buddies.

FN510 Tac vs. Glock 20.5

Hey! So I’m looking for a bear gun. Originally, I was set on the 510 tac. However, after reports of bad chamber support and the video of the frame splitting in half on Kentucky Ballistics, I opted for the Glock 20.5. After a recent realization about how poor the iron sights are and how bad it is ergonomically in comparison to the 510, I really don’t know what direction to go.

If you had to choose one pistol to trust your life to in the backcountry, in the most demanding scenarios, would you choose the 510 tac or the 20.5?

Thank you!

Springfield XDM 3.8”

Are you still able to purchase it either the HEX Dragon fly? Everywhere I look is out of sock in wondering if it’s just Springfield manufacturing falling behind or if they’re discontinued.

Weak sig V-Crown 180gr

Just came from the range where I tested some different ammo out of my P320 Xten and was a bit underwhelmed with the velocity of the sig ammo, especially out of a 5” barrel with defensive loads. Seems closer to .40 s&w than full power 10mm. What’s everyone running for defensive ammo for their 10mm?

Would you be interested in a 10mm Desert Eagle ?

I mean the real deal Deagle not the magnum research 1911

Out of handgun length barrels 10 and 357 mag produce similar muzzle energies and 10mm has a higher chamber pressure and uses a rimless case. My assumption is that this would make it more reliable than the 44 and 357 mag versions. But the Deagle is a novelty firearm so I’m curious to see if people would pick one up if they were ever made.

Holosun on FN510?

Ok, just mounted. Over/under on the 10mm recoil killing the 507k? Would be great if it didn’t, but thought I’d ask in case anyone has already tried this and succeeded…or failed.

G21 ➡️ 10mm

Dropped a 10mm conversion barrel into my G21.5.(45acp). Ran it Saturday for the first time. Ran perfectly. No issues at all. This one came from glock store- they were only place that had them in stock when I was shopping. Very accurate. They told me no need to swap the factory extractor in the gen5 and I guess they were right. No feeding or extraction issues.

Next time I want to run 25 and 50 yards from a rest just to see what we can do.

I also hope this barrel doesn’t have the chamber issues that I keep reading about with the stock glock 10mm barrel.
