Got back recently from moving my company's servers to America from California, me to follow soon. But while in California, I could not buy a Dan Wesson CBOB in 10mm, so I had one made with similar characteristics.
Here's what it's made of:
- Springfield 1911 frame
- STI .400 Commander length slide
- Bar-Sto ramped barrel. Frame milled to fit
- Barrel bushing custom fit by Bar-Sto
- Ed Brown bobtail mainspring housing
- STI grip safety
- Cylinder & Slide Tactical Match 4.5 lb disconnector, sear and hammer
- Cylinder & Slide firing pin for 9mm, .40S&W
- STI trigger
- 10-8 Slide stop for 9mm
- EGW flat firing pin stop
- 24# recoil spring
- Dawson Precision full length guide rod and bushing. One piece stainless steel.
- Novak bar/dot night sights
- Ambi slide safety
- Larry Davidson Gyro-Spiral grip panels (sans 'Spiral')
- Tripp Cobra 9 rnd magazines
This configuration has been utterly reliable with hot, mid-2000 era Double Tap 10mm. And, I'm starting to see the bottom of the 1000 round Georgia Arms 10mm ammo can I bought.
So, yes, they can be made.
