SLR15 1911 PISTOL ARMORER COURSE
When: September 24, 2018
Where: Sauk City, Wisconsin
We conducted a 1-day (8-hour) 1911 Pistol Armorer Course that was hosted by the Sauk City Police Dept. This was our 5th time teaching courses at this location, and we look forward to many more. The onsite facilities offer plenty of table space, decent lighting, and a large screen and projection system that allowed us to project animated graphics of the weapons system and powerpoint of detailed pics of gun parts, especially when looking at finer detail things like machining, stress cracks & wear. In this course we cover all variants of the 1911 Pistol system.
This class was a mix of Law Enforcement Officers from different areas agencies from around Wisconsin, and an Engineer from D&H Magazines.
The 1911 pistols in this class were a mix of Springfield, Kimber, Colt 80 series, Rock Island, Taurus, Sig Sauer, Ruger, Smith & Wesson, and Remington.
We started the day with going through the course manual we give all students. Students were supplied their own set of basic tools necessary to do most of the work on their pistols, and we passed out weapon and accessory specific tools as needed. Slip2000 "EWL" Extreme Weapons Lubricant & "EWL30", Slip2000 #725 Cleaner Degreaser, and Kroil was supplied to everyone. A short session of nomenclature was covered, at which time covered every feature and exterior part of the pistol was covered, to include all the hidden design features that most people are not aware of. Everyone was taught the procedures series of function checks, and safety checks that we recommend.
Next we covered the proper way to field strip their pistols, showing two possible procedures that are sometimes specific to the exact configuration for each particular pistol. Once pistols were field stripped, proper maintenance was shown of where and what to clean, how to clean it, and why some areas need specific attention that a lot of users miss. We also covered issues of using lead ammunition vs jacketed, and showed where and how to deal with lead fouling.
The Frame session started with the stocks or grip panels. We had several types of grip screws and everyone was careful upon removal. With the grip screws removed we inspected bushings. There were two types of grip bushings present, and everyone was taught repair and replacement procedures along with inspections and staking. Grip upgrades were shown and discussed.
We had everyone disassemble their frames. During this portion we showed how the pistol was designed to be its own tool kit for the field, and why we like properly fitting tools like punches and screwdriver (to include hex and torx). This class had three types of ambidextrous thumb safeties. We showed how all three types work and how they are to be properly disassembled and assembled.
The rest of the frame was disassembled, to include all parts (trigger, disconnector, sear, mainspring housing, sear spring, hammer pin, sear pin, trigger, magazine catch, etc). Inspections were done on all parts.
Note: A newer Remington had loose plunger tube. We see lots of loose plunger tubes from many different manufacturers, so this was not surprising. We brought a stripped frame with us, which allowed us to have people bed a new plunger tube, and stake it into the frame. When the student restaked his plunger tube using the Strobel staking too, which is our preferred tool, he somehow stretched his frame out of alignment. When he went to reassemble the frame and slide, the slide was rubbing on the frame of which it didn't do before the staking. Upon inspection, it was found that the frame was .004" wider in the area of the plunger tube, which is where things were rubbing with the slide. To fix the issue, he laid the frame onto the bench block and gave the frame a tap with a soft hammer, which put it back into the correct width so that it wasn't rubbing. This Remington pistol must have a soft frame, as everyone in the class had watched him use the staking tool, and when he fixed the frame with a slight tap from a soft hammer, which wasn't excessive or abusive.
The frames were reassembled and disassembled several times until everyone was comfortable. From there we showed differences in the internal parts. This allows us to cover the way parts are made and why and how sometimes parts have to be custom fit and tuned. We also covered several variations of internal safety mechanisms of the 80’s series and Swartz system.
We showed how to fit and perform trigger jobs, how to fixture and stone these for proper fit and function. There were several pistols with adjustable trigger, we showed how this adjustment works, and made sure everyone who had them, locked the adjustment down. We had brought a stripped 1911 frame and new frame components, which allowed people to go hands on and fit a few parts by stoning and filing.
Ejectors were gone through, showing several variations, and where and why some ejectors work better than others. We showed how to do ejector replacements and tuning.
Note: There were loose ejectors on a Ruger and Remington pistols. We showed how to tighten these up, which the people whom these belonged to made the corrections.
Once done with the frames we moved into the slides. Slides were inspected and disassembled including firing pins, firing pin springs, firing pin stops, 80 series type firing pin safety assemblies, extractors, sights, etc. Everyone was shown the differences between 70 and 80 series parts, and parts from multiple sources. Sight replacement, upgrades, and staking were covered. Most of the pistols present had internal extractors, except for the Smith & Wesson and Sig Sauer’s which had a external. We showed our preference for internal extractors. We went through inspections on the extractors and gauging. We also showed how to fit the extractors and adjust tension using the field method and the extractor tools (which is our preference). Once done with extractors we showed how we correlate the extraction and ejection,
The last session was spent on springs, spring tensions, ammunition, magazines, and everything that keeps the pistols running properly. We measured the strength of springs and several pistols present had too light recoil springs and main springs, we had a few replacements that we gave to those that wanted them. We showed the differences in magazine designs, and correlated this to feeding issues a lot of times can be attributed to having the wrong magazine. At the end of the day all pistol were reassembled, gauged and inspected.
Note: Several people found that their recoil springs were too light, several measuring in the 10Lbs - 11Lbs range. We showed why we prefer on 5" govt type duty pistols to use 18Lbs spring packs from Wolff, and what happens when spring systems are worn out or too light. It is our recommendation that one of the best and most important things you can do for any weapons that use spring loaded actions is to replace the springs on a regular basis, think of it like oil changes on a vehicle. When replacing springs on a 1911 pistol it is our recommendation that you change the recoil spring, main spring, and firing pin spring together. He was supplied with a new pack of Wolff springs.
