Hmm,,I know well over 2500 rds plus I put over 100 today at the range !!! Last time I cleaned it was Late Summer and I know I have at least 950/1000 rds since I gave it a complete clean job !! I have lubed it a couple times but that's it !! I hate to say it again,,but I love this friggin thing !!! I shoot reloads 99.9% of the time so any issues has been ammo related, high primer,,bad case,,etc,any Factory ammo has been flawless !!
