The Modified Glock

Glocks tend to run great out of the box.  They are reliable, and accurate.  I have a friend who shoots a lot of 3 gun and IDPA with a completely stock Glock 17 with the plastic sights, and does it well.  Some folks like to simply change out of the plastic “filler” sights that come stock, for aftermarket sights such as 10-8’s.

I like my Glocks a bit more modified.  Above is a brand new Gen4 G19 that is a recent acquisition.  The gun shot great out of the box, but there are changes that I like to make for my own benefit. Continue reading

AAR: 10-8 1911 Armorer Course, Phoenix AZ 08/17-18/2013

Another 1911 Armorer Course is behind us.  Before I get to the nuts and bolts of things, I would like to take a moment to thank those students who took time out of their busy schedules to spend the weekend training with us.  In addition to folks local to Phoenix, we had students travel from Massachusetts, New Mexico, Illinois, and Tennessee.  About half the students had taken the 1911 Diagnostics Course before, and one hardy student (thanks Rob!) had taken that course twice.  We were also very fortunate to have in attendance two of the full time professional gunsmiths from Robar Industries, as well as one of their marketing staff. With all those experienced 1911 users on hand, we were able to get to business and cover a lot of material. Continue reading

10-8 Consulting’s 1911 Armorer’s Course

Okay, I admit a little bait and switch. This is what we WON’T be doing in the Armorer’s Course. But we WILL be fitting extractors, safeties, and working on triggers.

After our recent series of articles on the 1911, many folks have gotten the impression that I am down on the 1911 platform, but this is not the case. I have carried a 1911 on the job for better part of 13 years, and dedicated countless hours and dollars to learning about and supporting the 1911 system. I think I speak for Hilton when I say our hope is to ensure potential end users go in with both eyes open should they choose to carry a 1911 on the job, or adopt it for team or agency use.

To this end, we offer the 10-8 Consulting 1911 Armorer’s Course. This is by no means a gunsmithing course, but goes significantly further than our 1911 Operations/Diagnostics curriculum in that it covers the skills necessary to perform basic maintenance and parts replacement. Unlike factory armorer’s courses, this class gives the student a broad spectrum approach to understanding how the 1911 works and will go beyond replacing factory parts. Included in the curriculum is a full overview of the cycle of operation as it pertains to the 1911, pistol and magazine maintenance, a full limited technical inspection worksheet, extractor replacement and tuning (geometry and tension), basic trigger work, and reliability modifications. We also provide an in depth explanation of the 10-8 1911 Function Test Protocol, where it came from, what it means and what it doesn’t mean. Continue reading

Bellevue 1911 Class AAR

We just finished our Duty 1911 Class at the West Coast Armory Range in Bellevue, Washington last weekend. Special thanks to Shelley from who helped us get squared away with the host site, as well as all of our students who worked hard for two long days and made the class run safely and smoothly.

During Day 1 of the class, we go over the nuts and bolts of the 1911, including a teardown and inspection of all student pistols. I worked on 15 of 19 of the student guns, based on deficiencies found during this inspection. The following items were addressed:

-Hex head grip screws stripped – screws removed and replaced with flat head screws
-Loose MIM factory plunger tube – removed and replaced with bar stock unit
-Cracked thumb safety (cast) – gun pulled from service
-Extractor tension/geometry corrected in 14 guns
-Hammer follow corrected on 3 guns via sear spring adjustment
-Barrel/feed ramp gap corrected on 2 guns
-Trigger overtravel adjustment corrected on 3 guns
-Mag catch trapping magazines – mag catch relieved internally

On Day 2 we headed to the range for a function fire protocol (sorry, it’s part of the class and doesn’t mean as much without all the context…so don’t ask for it to be posted here). A few more guns were found to be deficient, and the following items were addressed:

-Extractor tension corrected on 4 guns
-Feedway and chambering stoppages – feed ramps recut, chambers polished on 3 guns
-False lockbacks on 4 guns – slide stops clearance cut and detents cut

Of the 19 guns in the class, I worked on 18 of them. The 19th actually had feedway issues which were not brought to my attention until after the class was over, and I did not have a chance to work on the gun. One of the guns, an alloy frame 4″ barrel Commander style gun, was not able to be brought to proper functional spec with the time and resources we had available during the class.

The key learning point here is that the 1911 user must be educated and vigilant. Many guns that the owners previously thought were ok actually had some setup or function issues. Many of the required fixes were simple and only took me a few minutes in the classroom. After these easy adjustments, the same guns performed well on the range.

AAR: Duty 1911 Class, Liberty Hill TX

What better time could be had than spending two days in the Great Nation of Texas, devoting days to the quintessential American handgun, and spending nights enjoying Texas barbeque? I don’t know what the answer is, but 16 students had a great time testing out the theory during our Duty 1911 Class.

Students started Day 1 in the classroom at the Best of the West Shooting Range in Liberty Hill, Texas. Students went over the inner workings of their 1911s, detail stripped, and thoroughly inspected each gun. Any guns with identified deficiencies were addressed on the spot. Of the 16 student guns, the following issues were found and addressed:

  • 5 loose plunger tubes – restaked and Loctited 
  • 9 extractors – geometry and tension issues corrected 
  • 2 hammer follow issues 
  • 2 loose sights – set screws Loctited 
  • 2 sets of loose grip screw bushings 

Day 2 started with torrential downpour and a relocation to the Austin PD range. A brief on the fundamentals was followed by blocks on skill sets as they pertained to the 1911, including drawstroke, reloading, and malfunction clearances. Range time was capped off with a shootoff event fired on the new LaRue FAST target, an economical steel torso set up on a 4×4″ post.

We’d like to thank Black Hills Ammunition, LaRue Tactical, and Oakley for providing various items for the students, including prizes for the trivia challenges and shootoff event.
