(5 out of 5) Ruger SR22
by Dale from Philadelphia, Pennsylvania on March 5, 2016

Excellent handgun. Shoots just about anything you put into it without issue. If you have small hands, I'm a size 7, then this pistol is for you. Comes with 2 interchangeable grips.

(5 out of 5) Ruger SR22 3620 - Thumbs up!
by Greg from Niceville, Florida on June 16, 2016

Purchased an SR22 earlier this week and just returned from the range today after 300 rounds through it. At this point the gun likes high velocity HV ammo better than standard, though it cycled the standard velocity SV ammo pretty well. Used 4 types of ammo today: 100 Aguila HV, 100 Aguila SV, 50 CCI Velocitors, and finally 50 Remington HV Golden Bullets.

The Aguila HV was great - no issues. The Aguila SV felt underpowered and seemed to be a little dirty - I had one FTE and a couple of times where no new round loaded in the chamber. The hypervelocity CCI cycled well, but I had three FTLs. The Remington ammo ran well, but I also had 2 FTLs with it. I'm pretty sure a dirty feed ramp is to blame for all the FTLs from the Aguila SV.

So, in my first 300 rounds attempted with a total of 5 FTLs and one FTE... The SR22 is a wonderful handgun, very accurate, and I'm thrilled to have it. The 4.5 inch barrel is a plus, but does make it a bit more difficult to field strip the weapon. Aligning the longer barrel in the slide is harder than it looks to be with a 3.5 inch barrel because the spring/guide rod is shorter than the 4.5 inch barrel.

Looking forward to years of plinking with the SR22! Want to give a shout out to Sportmans Outdoor for making the purchase a very simple and quick process.

(5 out of 5) Worth it if you dont mind the wait.
by Q5tech from Fridley, MN on April 11, 2017

The Ruger SR22 4.5 is a good plinker. It's light and reliable. This gun shoots best with CCI mini mags or CCI AR rounds. The only con is that DA trigger is pretty long and heavy but the SA makes up for it. If you don't mind waiting a couple weeks, get it from here. The savings are will worth the wait.

(5 out of 5) Happy purchase. Browsing for another!
by Joshua from Houston, TX on July 15, 2018

I purchased this firearm back in May of 2018. Compared to other 22s on the market it's a fantastic gun, and a great deal from SOSS. Only issues I've had have been a few FTEs and FTFs but honestly, it's my fault for using cheap ammo. The gun performs well, and is a blast for plinking! After my purchase I had a small issue occur, but with a short call to SOSS customer service it was handled with ease. They were absolutely amazing and friendly during the call. Not only am I happy with the gun I bought, I'm happy with the company I decided to buy it from! I'm already looking for my next purchase with them.
