Thanks to my Shotgun, (MKA-1919), I am an open-division 3-Gunner. Last year, I spent a good amount of time and effort optimizing my shotgun to get it into the fight.
This winter, I’ve spent a lot of time building an Open division pistol. In for a penny, in for a pound, right?
The objective of my most recent range visit (besides spending some time with my 2 older girls) was to assess my latest upgrade to one of my Gen 3 Glock 19’s (codename “Roland 2). My baseline comparison was another Gen 3 Glock 19, (Codename “Roland 1”) which I have been working on all winter.
Both Roland’s have a Ghost Rocket 3.5 lbs connector, 13 lbs recoil spring, a Dueck Defense Rear Back Up Sight to mount a Trijicon Dual Illuminated RMR with a 7MOA Amber dot (my oldest daughters name is Amber, and my Modern Varmint has a Trijicon Accupoint with an Amber triangle).
Roland 1 has a Lone Wolf barre with a 1/2×28 threaded barrel that I mounted with a Rock Your Glock High Performance Compensator and a Zen Pro Magwell (purchased from The Shooting Edge).
I was shooting an IPSC Metric target at 10 yards. I hadn’t zero’d Roland 2 when I started and noticed there was a consistant pull to the left as I was shooting it. Hence, I took two strings as mulligans.
After encountering some reliability issues with Roland 2 owing to insufficient Power Factor, I resorted to doing drills just with Roland 1 (which has a more proven track record of good enough reliability, with most loads).
That’s one of the trade offs with running a compensated versus stock Glock. Glocks will usually run whatever garbage loads you run through them. It seems as if a 140 Power Factor is the minimum needed to run Roland 2 (although even that may not be enough).
Even swapping out recoil spring assemblies (down to a 13lbs in Roland 2, which gave it a disgusting trigger pull with problems with barrel lock up) didn’t help.
If I don’t get that power factor requirement down, I might have the slide milled with lightening cuts.
The drills I ran were:
- Controlled Pair (CP) from Compressed Ready (2 Hand, strong hand,
- One Shot Drill (OSD) from Compressed Ready (2 Hand, strong hand)
- One Shot, Reload, One Shot with Coupled Mags (1R1 MW) from Compressed Ready
- Draw / One Shot Drill (2 Hand, strong hand on trigger)
- Controlled Pair (CP) from Compressed Ready (Weak hand only)
Controlled Pair Performance for Roland 1 was pretty consistant with my previous 3 sessions (that I have data for).
My average Hit Factors have been 6.21, 7.43, 7.39, 7.43 (which was most recent).
Once I had zeroed Roland 2, the two strings were noticeably better: 7.42 and 8.86 respectively.
It remains to be seen if that was just a fluke, but once I get some higher power factor ammo, I’m going to do further testing to confirm.
I don’t have reliable data to assess the One Shot Drill at Compressed ready performance, but between Roland 1 and Roland 2, the average was very close (5.47 for Roland 1, 5.50 for Roland 2). With only 2 strings each, that’s too little data to make a conclusive comparison.
I have been consistent at performing coupled mag reloads with my Hit Factors being: 3.01, 3.09, 3.07 (most recent). 3 visits back, I did a comparison between the coupled mag reload and a traditional belt reload. It wasn’t even close – the coupled mag reload was much faster (2.66 average for the belt reload, 3.01 for the coupled reload).
Next time I go to the range, I’ll retest my belt reload versus mag wedge reloads to confirm the validity of that claim. With a single data point, the mag wedge load is definitely faster.
USPSA hasn’t banned coupled mags, so expect to see me rocking them this coming season – (see Sections 5.2.1 and 5.5 of the USPSA Multigun Rulebook).
I had slight improvement with my Draw / One Shot Drill. I only have 2 prior data points, 2.51, 2.95, and 3.04 (most recent).
I don’t have sufficent data to draw any conclusions about my weak hand, one hand, controlled pair performance, but it felt awful since it’s something I never practice.
I haven’t done much rifle work recently and even less shotgun, so I’ll have to meditate on some rifle/shotgun objectives.
Regardless, there’s still a little work I need to do to get Roland 2 especially to where I want it.
