Hello all. I know I am new in here but kind of have a touchy question. I am pretty new to firearms and shooting but it is now something i really enjoy. I easily drop 200 rounds when i go to the range which is once to twice a week. I have also figured out that ammunition becomes expesive depending on caliber and quantity. In my collection i have a glock 35 gen 3 and a glock 27 gen 4. I love them both, both weapons function flawlessly. i have considered purchasing one of the Lwd 40-9 conversion barrels to be able to shoot another caliber and save money on ammunition. I have yet to here anything negative about the product until today. I was calling local gunshops searching for one of the barrels and one of the persons i spoke to made the comment "no we dont carry those barrels, after 1000 rounds your slide is worn out." Now i am not wanting to start any arguments but does anybody have any long term reports using these barrels? Sorry for the long winded post.
