The 4.2" barrel version is available in some gun shops. Search this forum. Just a few days someone answered the same question that I asked.gringle84 said:Talked to Taurus today about another matter but did mention that I love my 24/7 OSS LS "Long Slide" version so far and asked about the "Standard version which has the shorter barrel. They said they only released the Long Slide version to the market and I didn't ask if or when the Standard version was due.
I can say that the 24/7 OSS LS DS is one very accurate firearm, I put 300 plus rounds down range today on it's first outing and zero issues, ran like a champ and ate everything I fed it from WWB, Speer Lawman 230grs FMJ to reloads with 185/200grs HP and FMJ rounds. It has a very short trigger reset making double taps easy. It has all the features I wanted in a firearm, match grade barrel .45 ACP high round count, single action/double action, cock n lock with decocker and also a striker cocked red tab feature in the rear of the slide letting you know it's ready for single action.
Whenever they release the Standard version, I'll have to get one of those to go with my Long Slide version.
