i has a rock optic cut & threaded barrel.

owned for a year now w only 2 mags through it.

both mags get hung up when inserting. i’ve tried and had others try to make sure it wasn’t me. nope. they get caught up on mag release or something on the mag itself.

it’s a JOY to shoot, but mag issue frustrates me. no, i haven’t pinged PSA. it’d take them 3 weeks to respond or offer RMA anyway.

Trade up to a S&W.

Fantastic handgun.

The CMR30 doesn't fold.  The SUB2000 folds, but it's in 9x19mm or .40 S&W.

Many of the bears in the lower 49 squeal & say,"Oh my God!" when a pistol is produced, let alone pointed at them.  5.7 can easily handle such threats, not so much your 9 ft tall monsters.

@PursuitSS

You can do a concealable 5.7 pistol, but you probably want to go to Bond Arms in lovely Granbury, Texas, for that, or you really will have nothing but a centerfire .22 magnum on your hands.

OP, how many 5.7 threads are you going to post in asking for 7 May sales?

I will say this, if the price comes down to 5.56 levels, or even better, 9 mm levels, I will definitely pick one up. But as long as it remains where it currently is, I’ll keep thinking about it.

It's warming up, and if PSA's MP7-at-home proves reliable it will probably replace my Rattler as my travel backpack gun.

There are more 5.7 guns than ever. It’s certainly not dying though I’d still call it a niche caliber.

It’s not the most balistically competent but 50 rounds of ANYTHING in a shoulder fired package the size of a computer keyboard is nothing to sneeze at

I reload 5.7x28 without any issues.
I simply wipe the cases down with a microfiber cloth once they are sized.
I use Hornady Unique case lube.

I am up to 5 loadings on the same cases without a single case head separation.

What bullet weights are you using & what velocities are you getting out of what length barrel?

Is there a market for spent 5.7 casings? I don’t reload but I’ve been saving mine in case there is

With the recent offerings in 5.7 pistols I believe the 5.7 is established.  It’s never going to rival 9mm or 556 in popularity, but I think it’s here to stay.  

I am, however, worried about a similar round I’m invested in, the .22 TCM, and more specifically its sister round the .22 TCM 9R.  It’s effectively a shortened .221 Fireball that pushes a 40 grain bullet to 2000 fps from a 5” 1911 barrel.  It’s a hoot to shoot.  The muzzle blast is incredible, but the recoil is damn near as mild as a .22.

Yep, when you've got less market penetration than .30 Super Carry, it's on life support.

I think it fills a niche. Wish ammo would come down, but it’s also not something I shoot as often as an AR or CCW.

I'd be more inclined to SBR it if we could also have the giggle switch.

FN USG

PSA Rock (2)
S&W 5.7

The S&W is by far my favorite pistol in the caliber, I love the ergonomics, almost ZERO recoil, great accuracy, 23 round capacity

I dislike the Ruger the most for NUMEROUS reasons. I cannot recommend it to anyone.

With Elite Ammunition S4, I’ve clocked it at 2,400 fps out of my FN MK II.

I trust the round so much that I carried it the last few years On Duty.

An FPC in 5.7 w/ a 16" barrel that takes the existing S&W pistol mags would change the game a little bit for me.  I'm gonna end up w/ $2k sunk into a Glock 26 9mm/5.56 Fold AR combo, if I could have a carbine that throws a rifle round & runs the same ammo & mags in the pistol, that might be worth switching to.
