I plan to try mine out on Thursday- I finally picked up some factory Sellier & Bellot 7.62X25, after owning the pistol since November. I plan to reload for this, as I'm not into dealing with corrosive ammo after every shoot, and besides- the bore on this pistol is hands down the best I've ever seen: glass smooth and mirror bright, although the feed ramp was rough to say the least. Mine is a 1947 Russian.
They're not the best fit in my hand, and I filed the right bottom corner of the mag so it didn't irritate my hand as much- that helped. Also, the rear sight has a U-shaped slot which is annoying, so I took a very small file and made the U into a square- no deeper or wider, just squared off the rounded corners. That made it much easier to sight.
I really like the clean lines- very little stamping, no ugly safety. Clean and simple.
I'll post here after I've had it to the range, but for the price ($169 at Lever Arms, came with holster, cleaning rod and spare mag), you can't beat it.
