The SR22 has always been a extremely reliable 22.cal. I shot so many rounds through mine, that it was worn out. I wanted Ruger to do repairs but they said it was no longer under the usual warranty. However, they would, repair the gun but I would have to pay for shipping up to them and they would do the repair and send it back on their own dime. Which was more than fair. However I made a list of many parts and requested they send me the parts which they did. I replaced a lot of springs etc. Great Customer service. One of the odd characteristics of the SR22 is the fact that it has some crazy ability to not get very dirty. I personally do not like the weird trigger which Ruger makes in so many of their guns now. But life if full of give and take so just accept it.
Mine is not very accurate, but for fast shooting at center mass is all that is necessary anyway. It is not a target gun.
All this said, the best Semi auto that I have and as totally amazed me is the Phoenix HPA 22. My gosh this gun is one heck of a sweet shooter and extremely accurate with nice sights and trigger. I can do some serious fast shooting with this gun. And cannot agree more with Gun Test magazine that said the gun shot better than guns costing 4 times as much. Heck my first one cost me only $85.00.
