How does it work?
The overall dimension of a barrel is kept, but the profile and the cartridge is the caliber change.
The overall dimensions are not the same, even the same gun manufacturer. If you have any questions, please do not hesitate to contact us. If we have a misunderstanding on taking the order,
Options for caliber change:
We calibrate you at the various guns listed, which caliber options there are. If the gun is not listed, then the following is valid:
Ie for .40S & W guns, options are: 9x19, .357Sig, 9x21
Ie for 45acp guns - options are: .400Corbon (not for each gun), .40S & W, .45GAP
Ie for 9x19 guns - options are: 9x21 (interesting for Italy) or other calibers that are based on 9mm (ie 9Steyr)
However, there are also manufacturers who produce all calibers with the same muzzle masks. Then, of course, the leveling up is possible, but practically not because the floor is matched to the original caliber.
