I have a MKIII stainless 5.5” that I bought used some years ago. It has run flawlessly, has a very good trigger and is consistently accurate. I’m usually pretty relaxed about specific features as long as the gun is well made and functions properly. It’s pretty straight forward. I just bought an NIB Buck Mark Practical for a heck of a good price but haven’t gotten it to the range yet. It seems decently built. The people I know who shoot Buck Marks like them a lot. I trust I’ll like it.
