I've been using a model 6280 (LvIII) for my XD40 and really like it. I'm also familiar with using a 6285 (LvIII) too. Since I've never used one, I'm wondering about the Raptor line. I have a Walther P99 and the Raptor fits it (Safariland doesn't have a P99 fit for their 6280 & 6285 models). I'm looking at the Raptor 6275 specifically. Are there any real differences/advantages in going to the Raptor? If so, what are they? Thanks!
