Introducing the Twin Roland Specials

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).

Roland 2 has a suppressor threaded Glock M13.5×1 LH barrel that I mounted with a TONI SYSTEM GLV6MI Compensator and a Magpul GL Enhanced Magwell.

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:

  1. Controlled Pair (CP) from Compressed Ready (2 Hand, strong hand,
  2. One Shot Drill (OSD) from Compressed Ready (2 Hand, strong hand)
  3. One Shot, Reload, One Shot with Coupled Mags (1R1 MW) from Compressed Ready
  4. Draw / One Shot Drill  (2 Hand, strong hand on trigger)
  5. 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.
