Surprised

Review by James M. on 25 Mar 2025 review stating Surprised
I recently qualified at the range. with my Sig P229. The DPM guide rod system preformed better than expected. The recoil did feel reduced, and the cycle rate was increased.
I will be purchasing more for other handguns.

20-round Mags

Review by Kelly G. on 25 Mar 2025 review stating 20-round Mags
For those who want them…I’m sure they’re great. For me, they stick out way too far. I returned them and stuck with the 16-round factory mags and simply bought an extension making them 19-rounders. The fit is flush now and that’s what I was after. Oh…Staccato C2, btw

Excellent Firearm.

Review by Baby B. on 25 Mar 2025 review stating Excellent Firearm.
Took only 4 days for my shipment to arrive at the local FFL shop. Everything was in order and CZ was already out of the shipping container when I arrived at shop. I guess that's the shops policy to open up shipments without customer being present first. Never saw container it was shipped in or packing slip by fed ex. Anyway all was good and I love the pistol. Already have a IWB holster for it and it is now added to my EDC rotation. Thanks Rainier Arms for the great customer service and timely processing of my order. You guys ROCK!!!!! Highly recommend Rainier Arms to anyone who wants their product shipped and delivered fast and in perfect condition. "Keep em in the 10 ring", G. P
