Things I liked:Fits well on a Walther P99. Designed/machined to close tolerances, allowing unrestricted slide motion while keeping a close fit to the contours of the weapon. Minimal intrusion on your down-the-barrel view. Easy to install. Top rail is sufficiently long to allow for mounting standard dual scope rings. Lightweight, with a satin black finish. Things I would have changed:I would have preferred machined aluminum. The plastic seems tough enough, but has a tendency to flex ever-so-slightly when mechanically stressed. The 2-part half-&-half construction of the mount itself (with no interlocking elements) struck me as a bit flimsy right out of the box, but with the mounting nut/bolt firmly in-place and the scope rings attached, it all holds together pretty well. I'm wondering if the mount's stability will be affected by the repeated shock of recoil. We'll see if this mount can keep me on-target.
I would also have preferred a faster on/off thumb-screw arrangement for quicker dis-assembly (Those little adjustment wrenches always seem to disappear on me). What others should know:Not a bad item for the price.
Things I liked:Handsome precision shooting instrument. Proper heft without getting tiresome. Excellent balance. I have a large hand so the grip just needed some light filing at the fingertips & thumb pressure points to customize a perfect fit. Even if you've been shooting for years, this pistol will teach you to become more aware of your shooting style. Responds to absolutely the slightest nuances of pressure and position. Fantastic. I've never shot anything even close to this pistol's elegance. Say what you like about Russian political philosophy, their engineering & design is top-notch. Things I would have changed:My M46 came with the "medium-coarse" iron sights installed. I switched to the finer front blade and got excellent results. I might file the sight blade a bit more...another 10-15% narrower would be perfect. A carbon-fiber cleaning rod might have been better than the included brass (less risk of damaging the barrel's fine internal rifling, especially near the muzzle). A wooden carry case would also be great. This gun deserves it. What others should know:Paul's video calls the front blade a "replacement" part, but it's actually an optional narrower sight blade allowing the shooter to customize/refine to taste. Similarly, the rear sight is reversibe (top/bottom) with a "coarser" and a "finer" window option, as does the 2nd (included) additional rear sight, so the shooter can choose from the four possibilities which option he wants. Nice set of cleaning and adjustment tools are included, as well as spare rubber seals for the pneumatics. It's expensive, granted, but rest assured you are getting world-class quality.
