Barrel class information

This information applies if you are taking the Barrel Class Only

The Class will start at 8:00AM

Please bring the following items with you the first day of class:

Bring your 1911 45 ACP government model for class. Please no Para Ordnance as it has an integrally ramped barrel, no Gold Cup or enhanced Colts as they have narrow hood barrels. Your pistol must be squeaky clean with extremely light lubrication. The pistol must be squeaky clean as dirt, carbon fouling, and excessive lubrication will interfere with proper match grade barrel fitting.


Cleaning rod and patches for 45 Auto

Roll of 1" wide masking tape

Mild steel rod 3/16" x 3" with a 3/4" long slot cut in one end centered (use hacksaw to cut slot)

Variable speed Dremel tool with 1/8" & 1/16" collets (If you are using a Dremel tool with

Screw driver or allen wrench to remove grips from your pistol

Tools to completely disassembly your 1911.

Dial Caliper - must be made of steel, not plastic, electronic okay but not recommended

(DO NOT PURCHASE inexpensive steel calipers designed for reloading use. We have found that they are not accurate for our use and tend to come apart. We recommend you purchase 6" Starreft dial caliper approximately $125.00 or 6" Mitutoyo caliper approximately$100.00. If you are unable to find these let us know and we will purchase them for you.)

If you take the barrel fitting school only the cost for parts, tools, and tuition is $1010.00.  If you are taking the barrel fitting school and the 1911 school together the cost is $560.  The reason for the difference is that you will have purchased about 1/2 of the tools for the barrel fitting school as part of the tools for the 1911 school.
