Modified Safariland 013 holster to accept a Arredondo Thumb Rest

I’ve always wanted to use a thumbrest on my Open race gun but could never get it to work because the Safariland 013 holster I’m using doesn’t have the clearance for a thumbrest as I’ve mentioned in this post : Arredondo Thumb Rest

I had to distract myself from some personal issues so I decided to take my new Dremel to the holster and make it work.

Here’s how the thumbrest fits on the gun :

 

First cut with the cutting blade. Yes I know, VERY sloppy.

Another view :

Test Fit :

Smoothed out the cut, and added Birchwood and Casey’s Metal Polish:

Fully assembled :

Final Fit :

Looks like it works! Now I got to get used to using a thumbrest.

9mm Major Chrono Results

Here’s the finished 9mm Major top end that John from http://www.jplprecision.com built for me.

Just took some different 9mm Major recipes with me to test. They were :

• RP 9mm Once Fired Brass
• 124gr Montana Gold CMJ
• Winchester Small Rifle Primer
• 8.5 – 9.0 gr of Hodgdon HS-6 Powder
• OAL : 1.165

I started with a 8.5gr load and worked up to 9.0 but we didn’t need it. If you look at the chart below, even 8.5gr of HS-6 was wayyy over the required powerfactor.

John’s load is a 7.6gr Silhouette behind a 121gr IFP round.

	8.5gr HS6	8.6gr HS6	John’s
Ave. FPS	1450	1467	1476
PF	180	182	183

The new KKM barrel is tight and very fast. Looks like I have to dumb down my loads to probably 8.2 or 8.3 gr of HS-6 powder.

New 9mm Major Top is done!

Just head from John (http://www.jplprecision.com)  that my new 9mm Major top end is done and ready.

here’s how it looked like while he was cutting it :

and the finished slide, top channel cut with 7 “Mitch” vents on each side :

The reason for all the cuts? To lighten the slide so it’ll reciprocate faster, while should lead to faster follow-up shots.

nice huh? Wait till I polish it!
