I carry the Longslide .40 and have shot it enough to make the grip slick and shinny in spots. I love it. I love Glocks and have never carried anything else on duty.
That said it is a Machine, all machines need maintenance. I don't care what others say about how many rounds they have shot through their Glocks without cleaning or new springs or any other claims of greatness. If you live by it take care of it. Change the guide rod spring and Mag springs annually. If you just shoot it at the range then abuse it till it breaks.
The .40 is a higher pressure round than the 9mm and .45. There are cases of the .40 blowing out the bottom of the unsupported portion of the barrel. Clean your chamber and don't shoot lead ever in a Glock barrel are the two most common guidance heard.
The Longslide 34/35 are the same length as a standard Govt. .45 so if you can carry a Gov't you can carry a longslide. The extra length helps with sight alignment and the length also helps with muzzle flip. Makes the .40 very controllable. It has a curious cut out on the top of the slide that most mistake as a Compensator. It is not, it is merely a slot in the slide with no corresponding ports in the barrel. It is said to lighten the slide and put the weight more into your hand to reduce the muzzle flip. They will come standard with the 3.5lb connector, extended slide lock and extended mag release. I swapped the 3.5 for the 5lb and rounded off the mag release with a fingernail board to stop it from rubbing my love handles.
As for the slick frame spots. I stippled the frame not long ago to fix this. The grip tape I had on it made the grip a bit thicker and eventually got sticky around the edges.
Fastest time was 4.0 for 8 hits from the holster. The rest was downwhill from there.
