I plan to pick up my new G27.4 in a couple months. It'll be like 'old home week' after so many years without a 27 (it was my first Glock back in 2004-05). With some advice from GT, I've decided to go back to AIWB with a Galco Ultimate Second Amendment horsehide holster, only I'm going to shuffle my belt buckle to the left and CC the gun at 12 o'clock. If the comfort factor is better than my old position of 12:30, I might consider getting a 9mm conversion barrel for summer carry and stay with the OEM .40 caliber barrel for cooler months. If I REALLY love it, I might sell my Sig P365 and stick with my three Glocks: a G23.2, the 27 and a G42 … all equipped with night sights and serving a different purpose. My supply of Federal HST 124-grain standard pressure loads is quite healthy, so I'd like to keep a 9mm in my limited arsenal, thus the interest in a conversion barrel. Figured I'd check out some reviews and then check websites. I was surprised (and disappointed) to see no 40-9 barrels on the Lone Wolf website. I recall using them in the past with other guns and felt they represented the best value for a barrel that seemed to work fine in another G23 with no other modifications such as extractor and ejector. Are there any other barrels I'm missing? The next step up is about $165 plus shipping compared to around $100 for Lone Wolf (if they showed a 40-9 barrel). Thanks for the input.
