My favorite Sig.
When production was still in Germany and around the time of the Service Pistol change to the Beretta the Sig P226 was actually in a tie with the Beretta but didn't offer the USA production and the bid was more expensive so we went with the Beretta.
Sig began offering a compact P226 as the 228. Many government agencies really liked the pistol and it gained a following as a Compact 9mm.
All pistols from Sig while in Germany had the Stamped Sheet Metal Slide @ that time: P220; P226; P228 etc. when production of the slides moved to the US is when SigUSA began using the Stainless slides on a Aluminum Frame and the P229 became the new pistol which was strong enough to handle the 40S&W and the Sig357.
I have both the 229 and the 228 and absolutely love the P228 the best. Great compact version of the P226, IMHO.
BTW, your making me feel old.
