I've got a semi drop in BarSto in my G22. It is so tight I thought it wouldn't function. It probably helped with functioning with a WML. It runs fine, and has broken in to a smooth operation. I don't generally measure groups, but it consistently shoots in the high 90's on a B8 @ 25yds. This is with CCI Aluminum blazer, which shoot very well in all my 40's. The G22 also has a "-" connector and Dawson adjustable sights, so that helps.
The only issues I have, and it's the same with my KKM and I think my StormLake...they do not function well with truncated cone ammo. I sent them out to have the chamber opened up, and some polishing, it helped some, but still not great. With most common ammo, the rounded profile flat point ball or JHP I have not had any issues.
On the metal guide rod in the Glock's, I'd be curious to know what the actual problem was that caused issues. I would think there had to be something not to spec in the rod...or the gun that a plastic rod covered up.
