This may be an option if he gets no satisfaction from CZ. His trigger may just need some adjusting, but my offer stands.

I hate MIM.

I've read that MIM parts have 95% of the density of real steel, but experience shows that there are potential flaws that often go undetected and can lead to failure. Magnafluxing or a similar process could probably detect the flaws, but it's unlikely to be done on a part made so as to save money. The adjustable sight on a Kimber Target II I bought for my son snapped off at the top of the dovetail, and as it was apparently pressed into place by a hydraulic press, had to go back to the factory. DF's trigger problem could have gotten somebody killed.

Kahr uses MIMed slide stops for their lower-grade pistols, but increases the diameter to compensate for the weaker material.

What fresh Hell is this?
