How does the Colt Delta compare to the Sig?
Don't get me wrong, I like Colts alot.
The Delta Elites are basically a 1911 designed for 45 ACP chambered for the 10mm. They really are not strong enough to take the 10mm the way the cartridge was designed. Most of the factory ammo is not loaded to the full pressures the 10mm is supposed to run at. Underwood loads full power 10mm ammo which cannot be used in the Deltas.
Dan Wesson, Sig, and Kimber are building their 10mm with a ramped barrel which gives the case full support. The Delta barrels are not ramped and the chamber is opened up to facilitate reliable feeding leaving the cartridge unsupported. Glocks chambers are not fully supported either.
The Sig is big, but the grips are very comfortable. The safety is a long reach for the thumb. I do not know why it was designed that way. That is my only gripe so far.
