I have both a pc9 and a pc40
They are heavy for what they are.
More accurate than you would think
And a fun little plinker.
Other cons
Hard as hell to clean
no longer available with decent sites (ghost ring) The mk2 adjustable that they come with is halfway up the barell sacrifising the site radius that the ghost rings had.
did I mention heavy!
On the good side, mags are cheep. You may have to mess around with them a little, opening up the feed lips etc. I ordered some from cdnn investments and changed the followes out to ruger factory and put +10% recoil spring in mine. I have over 1000 rounds through one mag with no problems.
Frequent mag problems with the cheeper mags is failure to hold the bolt open on the last round and failure to feed the last round.
They tend to favor the 147 grain bullets for which you can expect 3-4 in 100 yard groups fairly easily.
They are fun to add on to. The one thing you must have is an Uncle mikes buttcuff (similar to an m1 carbine) it holds two mags on the butt of the weapon. I also have a surefire barrell mounted and trijicon acog reflex on mine. Just for fun.
Some suggestions if you decide to purchase one.
If you favor iron sites as opposed to a red dot or someting along that lines (don't really need magnification with this rifle) get an auxzillary site from brownells for 60 bucks that fits ruger rings. This will give you ghost rings at the full site radius adding dramatically to your accuracy potential.
If you decide to go with a scope and you are not using factory rings (which don't come with it) make sure you get the jack weigand rail for it. There are others out there that allow you to put a weaver rail on top of your ruger rings but they stink. I bought 2 cheeper ones that both had screws strip etc before I spent the extra 5 bucks and got Jack's. Check out
