I'll play...
Taught a red dot handgun transition class for my department the last two days. This was our third class for the rank and file with the first two going late last summer. We are limited to an outdoor range and a combination of factors beyond the Iowa winter kept us from doing more than those two despite approving personally owned guns and optics last Spring.
Class attendance was twelve officers, all from our agency. Service length ran from pretty green to 27 years with us. This was our first class that I would describe as "mixed skill level." The first couple were mainly enthusiasts, but this one mixed in a few people who struggle at the range and have been convinced to give it a shot.
Guns:
Glock 17 with 509T (x2)
Glock 19 with 407C Green
Glock 19 with 507C Green
Glock 19 with 509T
Glock 19 with RM06
Glock 34 with 509T
Glock 43X MOS with 507K
Glock 45 with 509T (x3)
Somehow my notes are missing a gun...
All the guns were Gen 5 MOS with the exception of the 43X (obviously) and one of the 19s that was milled by Maple Leaf. I shot a 17 Gen 5 MOS with Steiner MPS. The gun and optic were brand new and I wanted to start with a clean slate to show zeroing. The MPS seems very nice. C&H was kind enough to overnight me a T&E (preproduction) plate for it so I could use it for this class.
Round count was about 700 rounds over the two days. The officer with the 43X was one of the ones that struggles and I will hand it to her putting up with that gun and firing schedule. She is a detective and was convinced by somebody else that the 43X would be easier to shoot. It obviously is not. Weather was trash at 40s, overcast, and relatively windy.
We had two optic plates loosen up (17 with 509T and 19 with 509T). Both were installed by me previously with C&H plates, Loctite 242, acetone prep, etc. I consider myself meticulous about the installs, but these two failed. They were re-installed with the same process and we're fine the rest of the way. The one RMR also started to go dead after the first day. The battery was believed to be original and 3+ years old. It was replaced.
Performance of the optics themselves was the usual boring fare. Nothing failed or lost zero. The guys with the green dots really dig them. I have one on a 19 and it works better for my eyes.
I remain very unhappy with the fit of Gen 5 Glocks with TLR-1 WMLs in Safariland holsters. Out of maybe six of those combinations, maybe one was serviceable. These are brand new 7360RDS holsters. I will be in touch with Safariland this week. I am of the understanding that they deny the issue.
This class gets out total deployment up to about 30-35 officers out of about 80. I suspect we will make it to the 50% mark before the year is out. This is significant because we did not allow personally owned guns until last year. The buy-in has been very good.
