I recently saw Walther's release of a set of RDS iron sights for the PDP. Because I'm a weirdo and constantly entertaining myself with thinking of out of the ordinary projects, I thought I'd try these sights on a G34 ACRO setup I've been putting together. Yes, Walther sights on a Glock. LOL
The gun in question is a gen3 G34, RTF2 frame, and a Brownells ACRO cut slide.
Basic Specs:
- Serrated front and rear
- .150" rear notch, .125" width front
- Stainless set screw rear, stainless screw front
- Square notch rear
Sight Dimensions
Dimension Measurement (inches) Front Blade Width .125 Front Blade Height .248 Front Screw Length .224 Overall Front Height .295 Rear Notch Width .150 Rear Notch Depth .114 Rear Blade Height .270 Overall Rear Height .352 Overall Rear Width .731
I have yet to test this combo, but a few things stand out. The rear blade height is similar to the factory Glock G20/21 height of .272. Also, in comparison with Warren Sevigny's for a G34, typically you have a .250" rear blade height and a .245" front. I suspect these are going to shoot high and I'll probably have to swap out the front for something between a typical .215" and .245". What's nice is, with this particular Brownells ACRO slide, the sights only appear to stick into the RDS window maybe 2-3mm I'd guess. It seems far less intrusive than a typical set of Ameriglo GL-429's.
Sight Fitment
Aesthetically-speaking, I am quite liking these sights! The edges are nicely dehorned. Not to a perfect degree, but the facets are such that there are no substantially sharp edges like there were with the original Trijicon HD's. Additionally, there is something subtle about these sights many might miss, but it's a nice touch and not one I've seen on many Glock irons before. The dovetail tenon has angled facets cut on all 4 corners. This makes insertion in the dovetail a breeze!
As far as the front sight, the screw is quite long. You get a significant degree of thread engagement with these. Fitment of the tenon in the slide cutout felt similar to most other sights I've used from Ameriglo, Trijicon, Warren, etc. Slight lateral play, but nothing major.
In the case of these sights on this particular slide, the rear sight fit into the dovetail by hand a little over 1/3. In my experience, often if they fit somewhere between 1/3 to 1/2, you can sometimes get away with a press fit without any filing. In this case, I was able to press the sight in with an MGW tool (MGW 309S for straight side Glock sights) without abnormal resistance, and with zero filing. YMMV The other nice thing is the cylindrical cuts present on both sides so you can easily use a round brass or aluminum punch to install, if you prefer, and without worrying about the punch slipping.
The fitment of the rear sight is good and does not have significant gaps anywhere. If viewing in front of a light source, you can see ever so slightly that the lower portion of the dovetail tenon is not exactly the same angle as the slide dovetail (at least with this slide). So you'll see a small amount of light shine through, but nothing significant. The level of resistance when pressing this sight in felt good, and between that fitment and the set screw + loctite 248, I highly doubt I'll see movement.
Range results to come...
