Thank you for your forum
I recently acquired an EAA Witness (manufactured by Tangfolio in the early '90s) with both the 9mm and .40 S&W slides.
This is a nice pistol, but:
The 9mm slide shoots 6+ inches low at 15 and 25 yards with 115, 124 and 147 grain factory loads.
The .40 S&W slide shoots 4+ inches low at 15 and 25 yards with 165, 175 and 180 grain factory loads.
The extractor of the.40 S&W slide was badly peened and deformed from (as I analyze it) hopping over the rim.
My best thought was adjustable sights (MECGAR) to repair the printing problem, but for the life of me, I can't seem move the stock rear sight. Measurement indicates that the rear-sight dovetail has a left to right taper (left edge is larger, right edge narrower.) I have tried standard drifiting ... no luck. I have used my sight pusher and after applying significant force, I stopped to get more information. I have used Kroil on the dovetails.
Are the stock rear sights on Tangfolio slides tapered and if so, how? Does anyone know the measurements of ths dovetail? I'll be more than happy to supply the measurements if I can ever get the things off
A quick calculation idicates that I would have to remove some 7/32 of an inch (.21875) from the front sight to regulate the sights and 'eyeballing' at the range confirms that almost 45% of the front sight height needs to be removed. if I can't install an alternate rear sight, does this sound reasonable?
Note that EAA has indicated that they won't be of any help or answer any questions.
Regarding the extractor: I ordered and installed a new one and the part # for the 9mm and .40S&W extractor are the same. After installation, testing shows that the next cartridge fails to slide under the extractor about 20% of the time under nominal conditions and 100% of the time if the next cartridge is pushed slighty forward in the magazine.
Is contouring the extractor hook normally necessary for the .40 S&W cartridge? I've done it many times, but my concern is that there is another problem disguised as a misadjusted extractor.
Love the pistol I mainly shoot .45 ACP and have a CZ 97 ( a real CZ.) I acquired the Witness quite comfortably and I don't mind spending time to make it work well.
