I have been given the rare chance to try an open gun for a couple of weeks before I buy it. I have limited exp. with this type of gun. first the gun. It's an sv frame, caspian 5" stainless slide, barsto .355 38super barrel with a serendipity sl c-more. The ammo I was given is a mix of 38 super and 38 supercomp brass the gun runs both flawlessly. which is better? Next the mags(140mm) have funky plastic basepads that slide almost off the mags when you seat them and you can not put more than 22rds in them or they get stuck at the bottom. What can I do to fix this? lastly I want to get a big stick for this gun and have seen some of the other posts talking about mag interchangabilty. Which one do I want? any help you guys and gals have would be great ! Also any good loads for 125 zero bullets thanks??
