I love mine, tight fit is a good thing for me! Tons of features killer price too.

We got one when they first launched, it fit tight on the upper initially, but I appreciated that as it shot tight groups. Over time the pins loosened up, the lower still fit tight and there was no slop, but the accuracy was great with my Foxtrot Mike 8.5 Upper

<br>Cant complain with what you get for the $$$

Fun little gun!

Did 400 rds at the range today, mostly cheap stuff, it ran Seller Bellot and Silver Bear with only 3 light strikes all day, no ejection malfunctions. I was really liking the gun and thinking maybe it would be a good house gun. I loaded 5 rds of Hornaday Critical Defense to check for feed issues. Sadly, 3 out of 5 rds didn't fire. The rounds fed but got no strike on the primer. This was after 400 rounds, I'll try again next range day with a clean gun.

<br>The primary mag well has a bit of a flange that really helps get the mag in there. The only issue I was when I did some movement drills with it and I had a 30rd mag in the grip well. I guess the mag was too heavy, every few rounds the secondary mag dropped. Glad I was alone. When I switched to G17/19 mags this wasn't a problem.
<br>
<br>Overall, fun gun and I'm happy with it. I'll make a final decision on reliability after I put 1000 rounds through it. At about $600 total for the built this was a great purchase. Do it.

Looks nice and has some cool features but way too many fitment issues

by -

1, None of my Glock magazines fit into the magwell or spare mag holder without a lot of effort. The fit is too tight. Have to push hard to get them to seat. I have tried factory Glock magazines and 3 brands of aftermarket magazines.
<br>
<br>2, The front pivot pin is WAY too tight even after oiling it. Even without an upper receiver installed I can't move it without a punch & hammer. The upper is hard to swing open because of the pivot pin.
<br>
<br>3, The head of the rear takedown pin is countersunk so it can't be pulled out like a normal pin. It needs an extended pin but a regular extended pin won't fit because of the way it's countersunk. This is a bad design because it prevents opening the upper to clean or remove a jam without a tool to push it from the other side.
<br>
<br>I'm replacing the current lower receiver on my pcc. I could sand down these parts to help with fitment but a lower receiver this expensive shouldn't have so many fitment issues.

Inovative features, and one of a kind.

Front take down pin, super tight, had to remove and dull the point a little. Front receiver hole off location slightly, binds against upper when closing, but not a serious flaw. No fire control guts, you have to buy that extra. Rear grip/mag. holder works, but is sloppy and a distraction until you get used to having that extra feature. What I don't like is the shape of the grip. Don't fit my hand, or add to working the controls. If you use the FM upper, when cocking the pistol, the grip shape drives the web of your hand into the buffer lock plate. The bolt hold open feature works, but the button is a little small.

Tight Fit

by -

Just purchased the FM 9mm to go with my FM 9mm upper. The take down pins were very tight fitting. Had to modify the lower to make the upper fit. The bolt locks open with a magazine. Seems to function well during dry fire. Will need to take it to range for a test run.

A lot of unique features for the money

Nice lower. Has a lot of unique features like last round hold open, ambidextrous safety and mag releases, comes with pins for trigger and upper. Holds a spare mag. Used a BCM PNT trigger with JP springs with no issues. They cast a "cam" surface into the front pivot pin that pulls the upper tight when you mate them, nice touch there. A lot to like for the price.
