    The only thing that was not good is that the slide and barrel is too tight where it’s hard to chamber. It does cycle on its own afterwards.

    Nice slide, took three weeks to receive after being sent wrong product. Even then barrel is suppose to be a 27 not a 23 chopped down without polishing crown. Little disappointed.

    well it took awhile to finish my building of a glock27 with a 80% kit. I looked on the web and looked for the best deal trying to keep cost low. new glock slides were running 450 dollars, some used slides were 400 plus. I just got done building a g22 and 23 and parts ran 300 to 340 dollars for complete slide and barrels no extras, so when I started looking for parts to build the g27 I was shocked how so much more the slides and barrels were.i called rock slides USA about availability and they couldn’t give me exact time but they said soon. a few weeks went by and I went back to there web site and they had my parts in stock.i was just going to buy a slide and barrels but there prices were so good I bought a complete slide( slide and parts kit, sites, and barrel), barrel, three mags and mags loader, factory Glock case, cleaning tools and lock. all this 404 dollars plus I think it looks good. rockslides products are well made and work really good. iam very pleased at the quality of your product and will buy more in the future.the order got to me real quick, I was impressed. I hope to give more reviews in the future I have a g22 and g23 and want to customize them soon. great product and service i will highly recommend your product and company. and they are made in the USA. THANKS
