I've been looking at but not shot my "new to me" but used P3AT. I disassembled it today and noticed it has a steel not polymer guide rod which I'm assuming was aftermarket by the previous owner. My question is this - my slide comes back very easily about 1/2 of an inch when retracting it, as in when I use the beltclip to hook it IWB, I sometimes feel the slide move back just a little. Is this normal is my spring(s) sprung? I don't want to unnecessarily replace the springs but if this is too weak I would want new springs. Any info anyone can give would be great. Thanks.
