Generally, yes. Trust, but verify.
I somewhat recently purchased an H&K VP9, the newest Optics Ready version. Also one of their mounting plates, which I used to attach a holosun 507.
As H&K hates me and did not see fit to include iron sights tall enough to actually use with a plate mounted RDS, so after my first outing with the RDS and too-low irons,I ordered a set of lower 1/4 witness height suppressor/RDS sights from hkparts.net
I installed these sights using a Midwest Gun Works pro style sight pusher with VP9 shoe, as I have done to many pistols many times. Everything seemed normal. I took it to the range. All good. Took it to the range again, still all good. Started carrying it.
Took it to the range again today, and wouldn’t you know it, the darn iron sights failed. The front sight, which is a simple press/friction fit, and had remained in place through the first one or two range trips and time EDC’ing and dry firing, suddenly was sliding back and forth from one extreme to the other, left and right, it seemed ready to come off the slide entirely.
Good thing I had that Holosun RDS
Now, granted, I have swapped a lot of iron sights onto a lot of pistols and shot a lot of rounds over the years, but, this is the third time I have had iron sights fail. knock on wood I haven’t had an RDS, rifle or pistol, fail yet.
Not even sure how I’m going to fix this, if it is too loose, it’s too lose. Going to have to start again and pull the RDS again to pull the sights and replace with something else. sigh
(the other two iron sight failures were a Glock front sight I didn’t use thread locker on, and a Glock front sight I had installed by an LGS many years ago, because they didn’t use thread locker…had to learn that lesson twice in a way)
And note that it took hundreds of rounds for this failure to manifest.
