Was running a Yankee Hill suppressor on a Walther SP22. No noticeable shift in POI. Found out my S&W 422 has a threaded barrel.
Installed the adapter and suppressor. Tightened up adapter the same as original barrel, very tight. Took out and sights were still spot on. Installed suppressor and now POI is off 6 inches high and left.
Grouping is still tight. This is at 12 yards. Took suppressor off and back to spot on. Reinstalled and tightened up suppressor on adapter really tight. Still high and left.
The Walther has zero shift. S&W 422 so much I hit a 6” plate once in 10 rounds from 12 yards. Shifted aim low and right. Ran off 30 in a row. Removed suppressor and shifted sight to center and ran off 20 more.
Six inches at 12 yards is crazy. Will check to see if suppressor is cocked off by the thread adapter.
