I don't have a polymer tanfoglio ....yet. I was hoping to get the force pro.etc with rail in either 9mm or .40. I tried a .40 at a local shop and liked that I could reach the mag release easily, and since I use the stock 2, Limited custom, and recently got a 38 super open gun..it is very easy to adjust to the polymer grip. I felt the trigger was a little heavy, but was smooth enough in DA and SA to be competitive. Some light polishing and in IDPA, you could get a lighter spring set up. Not sure about holsters...but my research suggests a fobus (blech,...cough blah)...for a sig works. The model is named as witness P on the fobus website. I assume the sig model holster that shares the model number for the witness may also work for the bladetech series.
My older stock2 9mm has at least 60-65000rds thru it. I broke my rear sight last year about 1 week before the NS provincials. Sean at Freedom Ventures had me a new rear sight in about 2 days. Great service. Why did the sight break....? Parts break...and after that many rounds and dryfire, handling..etc... I would expect something to have broken.
My .40 might have 10,000rds thru it, only thing I ever did was trim my slide release lever because I was using aftermarket 10mm mags....my back up gun stock 2 might have 5000rds thru it....no serious issues. Might have 1000-1200 .22 rounds thru my .22 top end....
