Got a PSA Rock 5.7 Pistol

After doing a lot of research, last Sunday I ordered a Palmetto State Armory Rock 5.7 pistol, and I was able to pick it up from my local FFL on Wednesday.

A picture with my Beretta M9 for scale:

(The Beretta has slimline grip panels from LOK Grips, which I can't recommend highly enough. They really improved the feel of the gun for me.)

5.7x28 is a bit controversial among shooters but I decided to try it for a few reasons:

• The ballistics from a handgun should be similar to .22 Magnum from a rifle. Obviously, from 10+" barrel 5.7 will have significantly better ballistics. Based on what I've seen on YouTube, the AAC 40 grain loads should give me around 1800 FPS from this pistol's 5.2" barrel.
• Mild recoil.
• The pistols have the reputation for being easy to cock, which is good for people with hand problems.
• Very high magazine capacity.
• Lightweight, compact ammo. A 50 round box of 5.7x28 is not much larger or heavier than a 50-round box of .22 Magnums.

This picture shows a CCI Blazer Brass 9mm 115 grain FMJ round next to an AAC 40 grain VMAX 5.7x28 round:

Here are the specs of the package I bought:

• Two-tone sniper green/black
• Optics ready
• 5.2" threaded barrel (1/2x28 threads)
• 10 x 23-round magazines
• A soft case.
• Gun lock.
• Chamber flag.

The cost was $599 + tax and shipping. My FFL charged $30 for the transfer.

This will be my first foray in 5.7x28-land. At some point I'll probably add a Holosun 407K but first I want to try it with irons.

After I I ordered the pistol I also ordered 300 rounds of AAC's 40 grain VMAX load (they were out of stock of their FMJ loads) and one box of American Eagle 40 grain FMJ. When I picked up the gun I also bought one box of FN SS197SR 40 grain VMAX loads.

Yesterday I got a restock notice from PSA and ordered 250 rounds of their AAC FMJ loads.

Fiocchi is now selling 150-count bulk packs of 40 grain FMJ rounds. At some point I'll get some of those because they end up being the least expensive practice rounds.

My initial thoughts without having fired it yet:

• The grip is nice. My hands are on the small side but I have no problems gripping it comfortably. The grip reminds me of a S&W M&P-9.
• Good three-dot sights made from metal. The gun can be fitted with any Glock-compatible sights.
• The trigger pull is heavy but has minimal takeup and a short reset. No noticeable creep. With some lubrication and dry firing I'm already noticing an improvement.
• The finish on the slide is nicely applied.
• The magazine catch is a bit stiff but is already breaking in. The mag catch is reversible but even though I am left handed, I will leave it as-is. I used my middle finger to push it.
• The takedown procedure is the same as a Glock but easier because of the design of the takedown latch. Putting the upper back on the frame is a little different because of the takedown latch.
• Field stripping and reassembly are easy. The takedown catch is much easier to use than on a Glock.
• The zippered case that it came in is very nice.
• The owner's manual is very nice and printed on good quality, glossy paper.

I will shoot it first with iron sights but plan to mount a dot in the near future. I should get to shoot it this weekend and will post a range report.
