Question: Wondering if this would fit on a Walther PPQ M2?
Document: DOA! Tried three new batteries but still would not work. Contacted Amazon and they shipped out a replacement that same day. Second unit worked fine.
I especially like the pulse mode feature. It also came with a pressure switch for AR platforms. All in all it seems to be a great laser. Of course with a laser on your weapon, finding a CCW holster to fit is nearly impossible so, I cured that with a Glock Grip Clip which allows cocealed carry even with any laser. It can be worn with light clothing without &#34;printing&#34;. Thus far I am very pleased with this purchase.
This item is a great addition to my Glock 19. The bottom of the laser is flush with the bottom of my trigger guard and the front is flush with my slide. It is actually a bit larger than it appears. However I noticed it added just enough weight to the firearm with a full magazine to add a great balance when aiming. I installed this laser in about 10 minutes. No windage adjustment was needed. Just a minor elevation adjustment was made. The laser itself is very bright and easily accessible from either side.
Answer: no
