10x bushing install change POI?
« on: February 08, 2020, 07:59:44 PM »
I just got my slide back from having cajun install a 10x bushing.  Its a CZC SP01 Shadow.  It could have just been an off day for me but I felt like i was significantly high.  Is it common for the bushing to change point of impact?

CGW 10x bushing basically keeps barrel tighter, so perhaps now your pistol has correct POI?
What is your sight picture now? 6 o'clock?

Yes it possible. Barrel is locked up in different but consistent location. So impact can be different

My pistol (TS) shot 3" left, 1" high, at 25 yards after I installed the 10X bushing. Different pistols would show different results, depending on manufacturing tolerances between different parts, namely the slide at the muzzle (where the bushing fits), and the OEM bushing itself.

POI seemed to be about 1ft high with a 6 o clock hold. at about 15 yards  With non adjustable sights what are my options as thats too far off for adjusting hold.  Gun was super accurate.  Maybe i didnt need to go this route.

1 ft at 45 ft ?  :-X :-[ :'(
That's huge distortion. Have you contacted CGW?
Answering your question -> if your pistol was accurate, no reason to use 10x bushing. I had great conversation with David from CGW about this and he told me to not touch it if is accurate enough.

I see two resolution for this:
1. come back to original bushing
2. change front sight (if possible) or both, based on Dawson Precision Sight Calculator:

I just ordered the 10x cgw bushing for my shadow 2.  Reading this I’m not sure if I should install it.

Any reason for new bushing?

I've installed two 10X bushings and my results went like this. 

The first went on a S2 upper that had came back from being milled.  I didn't notice that the front sight was missing and the bushing went flying after about 20 rounds and I never found it.  Once I had the 10X bushing installed the S2 seemed to be a little more accurate with a only a small tweak to DPP.  The barrel was a little more difficult to remove, but manageable.

The second was on a 75B that always shot well, but had 15,000 to 20,000 rounds through it.  Since I was changing the sights I figured that a new bushing was in order.  I installed the new bushing and the groups were tightened up noticeably, but not dramatically. The sights didn't need to be adjusted very much.  The barrel on this one is a little more difficult to remove, but I can live with that also. 

Given to go through  this again, I would without hesitation.
