Pedler:
I can't give you quantative statistics but I have observed this particular problem more in DT-10's than in any other gun in Beretta's line up or anyone else's. In the last month I have encountered it with three of my customers, and I have either sent or reccomended that they send the gun to Rich Cole to have it corrected.
I can't tell you how many times the guns were fired or what the handling conditions for each gun was. I would hope that this is an issue that Beretta has addressed in it's current production DT-10's.
