I picked up a used P232 LE package with NS, 3 mags, and the gun looked like it had been shot very little. There was a little surface rust on the barrel, but the gun smith at my range got that off. He said there might be a little pitting but it was more rust than anything. It was a bit of an impulse buy as I have a liking of the P232. Yes it's not practical, but they are easy to shoot for me and one of the few guys I actually enjoy shooting.
When firing FMJ ammo the only problem I had was with one round. However the hollow point situation was totally different. It would feed some, but had many Failure to Feeds. The problem would either happen when trying to load a new magazine into the gun or when firing the gun. The new round would be stuck at a "45ish" degree angle. Sometimes a bump on the slide would seat the round, sometimes not.
I doubt sig would honor the warranty now. Not saying they should either, it is a used gun.
Thank you for any help you give and please let me know if I need to clarify anything.
