Problem with HAJO Adj Rear Sight
« on: September 28, 2013, 02:03:12 PM »
I bought my 75 Custom Shadow last April--I think, and had the HAJO adj.-height rear sight added on.  The pistol's shot over 1000rds/month since then.
I later heard about one guys HAJO  sight, that the adjustment screw broke off while shooting a match,  so I bought a spare ($9) that includes the two tiny spring that will go flying when the screw breaks.  I don't know if this was the first such breakage or not, but I did hear something about getting harder steel for the screw.

It happened to me this morning, also at a match :'(.  The screw broke off right at where the screw machining stopped and the round cog-wheel head with a hex hole was cut for the adjustments.  When the screw broke, the sight flips forward and the two springs went flying, but I did find the 1/4" wide head with the hex-hole.  You can see right through the hex-shaped hole where the screw used to be.   That hex-shape was cut all the way to touching the screw body,  only very thin steel left holding the threads to the head.

I finished that stage when the sight broke by point shooting my way to a bad score. 
I did get my pistol back together with my spare parts for the next stage, and got the sights back close enough to run a steel plate-rack.  Still left smiling.
I REALLY like the sights, but I hope a stronger screw is coming.   

Just giving other owners/potential buyers a heads up for "possible" problems and/or spares needed on hand.  Maybe yours will hold together.

UPDATE:  There is a 'new' improved screw available.   If you like the CZC Competition sight, this height adjustable version is it's smarter twin brother.   Life is good again.  8)
UPDATE #2:  I came in 3rd overall in the match and second on the "BUG" stage with my Sig 239.  If I'd had a PO1 or CompactL, I might have moved up a notch.   ;) ;D

Thanks for the heads up. It appears that users should get the upgraded screw before it is required.

The sights are a definite must have for Shadow owners.
Life is too short to waste on a bad trigger pull
