Yes., a few people have had problems. Just like a few people have had problems with their Glocks/Sigs/S&Ws/Paras, and dare we say it, CZs. It's not a systemic failure, if it was there would be stories with pictures and law suits all over the place.
Just shoot your gun(s), and then if you have problems, deal with it and feel free to post, with pictures.
In future, any anecdotal stories about cracked slides are going to be locked/removed on sight.
Ps. If anybody has created any 'sock puppet' accounts on here for any reason, that member will be banned, no exceptions.
Locked.
