The following should help guide you with the selction of a Mech Tech CCU


1 - 1911 FRAME COMPATIBILITY

The 1911 and the Mech Tech CCU have a very strong and easy relationship. Unlike the Glock pistol, which requires different CCU's for large frame and small frame guns, all 1911 pistols can use the same Mech Tech CCU (caliber differences aside).

The length of the 1911 frame dust cover has no effect on the frame's ability to mate with the CCU. The CCU will accept a Colt New Agent as well as a full size Remington, or Armscor or any other manufacturer's Government Model. We often use the Shooter's Arms 12 shot compact with the CCU. Additionally, the Mech Tech CCU when mounted on a 1911 allows the 1911 Hammer Safety to be utilized, which gives the Mech Tech the same level of safety that most rifles have. Extended safeties may present a problem, but all original size safeties function flawlessly. Although, Mech Tech (As stated below) states that ambidextrous safeties will not function, the Shooter's Arms FX Lightweight safeties function fine. The Telestock may need to be canted slightly to clear a safety. When using an ambidextrous safety with the Telestock, the stock must be centered, and partially extended to use the safeties; and the it work fine. The problem is with larger extended safeties.


2 - 1911 NOTES

There is a certain 'juggling' of calibers relative to the CCU Upper of which one may take advantage. The 1911 pistol frame is designed to accept 1911 magazines of several different calibers. The proper magazine for your pistol is of course that for which the slide and barrel is designed. The fact that a 1911 magazine of a different caliber will function in the 1911 frame (when the frame is separated from the slide and barrel) allows one to order a CCU chambered for a cartridge different from that of the assembled pistol's frame you plan to use with the CCU Upper. Example: if you have a 1911 which is designed to fire 45 ACP cartridges but you would really like to have a CCU in, say, 10mm. You can then order a 1911 style CCU Upper chambered for the 10mm cartridge and use the frame from your 45 ACP pistol with that CCU. You will need to acquire a 10mm 1911 style magazine and use it only when using the 45 ACP pistol frame with the 10mm CCU. CAUTION: this does not mean that you can use your 1911 pistol to safely fire a cartridge other than that for which it is designed by simply switching magazines - don't try this - it is dangerous! The barrel and slide of a 1911 pistol is designed for a specific cartridge and only that cartridge is safe to use when the pistol is assembled. Likewise, a CCU used with a 1911 pistol frame (lower unit) can safely fire only the cartridge for which the CCU is designed! This information is provided only to illustrate the flexibility available for 1911 style pistol frame and CCU combinations. Again - your pistol should be used only with the cartridge for which it is designed and a pistol/CCU combination must be used only with the cartridge for which the CCU Upper is designed. If further clarification is needed contact us directly or Mech-Tech Systems Inc.
Last Round Hold-Open - there is no last round hold-open function on the CCU.
Safety Lever - only the original GI style safety will function with the 1911 CCU. Extended and ambidextrous safeties (See above) will not function as a safety but the CCU will function and fire in all other respects.


3 - GLOCK NOTES

Glock C.C.U. Upper is available for the following Glock models:

G17; G17C; G34; G19; G19C; G20; G20C; G21; G21C; G22; G35; G22C; G23; G23C; G31; G32; G32C and the respective 'SF' models - (All Gens)


4 - GLOCK NOTES FRAME SIZES

Glock pistols are made in three basic frame sizes - 'Full Size', 'Compact', and 'Sub Compact'.

MECH TECH UPPERS ARE NOT AVAILABLE FOR SUB COMPACT GLOCKS

If you own more than one Glock Pistol of the same caliber, but of different frame sizes, check below to see which of the three different CCU's will fit which of your guns.


5 - GLOCK FRAME SIZES AND COMPATIBLE MECH TECH CCU'S

In the Standard size series there are two frame widths that are compatible with the Mech Tech CCU.

In the Compact size series there is one frame width that is compatible with the Mech Tech CCU.

1)   STANDARD (Full Size) series are the Models:

A)  LARGE (FAT) FRAMES :

G20 (10mm) 15 Rounds
G21 (45ACP) 13 Rounds

B)  SMALL (SKINNY) FRAMES :

G19 (9mm) 15 Rounds
G23 (.40S&W) 13 Rounds
G32 (.357 SIG)13 Rounds


6 - GLOCK MAGAZINE INTERCHANGABILITY WITH A PARTICULAR CCC

A frame separated from the slide and barrel will physically accept a magazine of a cartridge different from that for which the assembled pistol is designed (using magazines designed for the same series of frame sizes). Therefore a Glock pistol & CCU combination can be set up to safely fire a cartridge different from that for which the assembled pistol is designed.

Example: The frame (lower unit) of a Glock designed to fire the 45 ACP cartridge in the assembled pistol can be safely used with a CCU Upper designed to fire the 10mm cartridge. This is accomplished by assembly of the 45 ACP Glock frame to the 10mm CCU and the use of a Glock 10mm magazine designed to be used with that series of frame size. This information is provided only to illustrate the flexibility of the Mech-Tech CCU.

CAUTION : the foregoing does not imply that a Glock pistol designed for a given cartridge can safely shoot a different cartridge by simply switching the magazine - this is dangerous - do not try it! Likewise a CCU Upper can safely fire only the cartridge for which it is designed!) If further clarification is needed please contact Mech-Tech Systems Inc.


7 - .45 SUPER


There is a difference in the regular configuration of the 1911 .45ACP CCU and the 45 Super configuration. Survival Outfitters offers the conversion at no cost, shipping aside. Since the external dimensions of the .45ACP case and the 45 Super case are identical, a CCU properly configured for the 45 Suoer will will handle either round. Many people choose to have their 45 ACP unit 45 Super ready. Any 45 ACP 1911 CCU ordered from us may be ordered configured for handling the 45 Super. Using the more powerful .45 Super takes full advantage of the CCU's potential.


8 - .356 Survivor


Survival Outfitters is currently working on a proprietary cartridge that may be fired in properly configured and rebarreled .45ACP guns. We will be offering this special chambering for the Mech Tech CCU. The cartridge is based on .45ACP case dimensions with .38 Super length, formed from .308 brass and necked down to 9MM. It will use standard .45ACP magazines. Think of it as a .357 SIG on steroids. Rollout date to be announced, and we will begin taking orders at that time.
