Purchased the pistol and barrel long before the tactical version came out, have 3000 rounds through the pistol without a single malfunction. Can paperwork finally came in and was able to shoot the illusion over the weekend, 100rds of 147gr and functioned flawlessly with original recoil spring. Plan was to buy the new HK tactical barrel and the VP40 recoil assembly but not sure its worth it as I have had 0 issues thus far. Anyone in a similar position?
