A little more thinking on the Shield RMS ... paging Vinny ...

[bpnkrtn]

I continue to be more than satisfied with the Shield RMS and CZ 75 Compacts.  The RMS co-witnesses with factory sights quite well on the P-01.
I do prefer the PCR (picky, picky).  I have a PCR with all the CGW goodies, Pro-package, bushing, and a set of CZC sights that I really like (if I could see them).  They work well with my shooting glasses ... but I'm becoming more and more of a convert to red dots/optics.

I tried to remove the rear iron sight on my P-01 to see if I thought the "notch" in the RMS would be adequate as a BUIS.  I think CZ must have wielded the rear sight in the dove tail!  Now, finally, the question ... do we think the RMS notch would function adequately as back-up sights in case of RMS failure?

The loaded chamber indicator (LCI) on the PCR and the strange/odd/unusual rear sight cut in the slide make the PCR a little more difficult to mill than the P-01.  My thinking is to mill the PCR for a RMSc, using the rear dove tail slot as part of the milled area, using the "notch" on the RMSc as the back-up.  That seems to be a more "elegant" solution (or maybe I'm just still hallucinating from 20 hours of graduate level statistics courses?)

I appreciate all thoughts, information this esteemed forum can offer ...

FYI/FWIW ... after finding the PCR I'm selling many, if not most of my other pistols, so I'm generating some money ... which would allow me to buy another PCR for milling and the full CGW treatment ... life can be good for a retired old fart ...

With practice I would say, yes, you can go without a rear sight. The optic itself is a good enough reference point for effective hits out to reasonable distances.

With practice...

+1 I agree with s0nspark.
It is after all BUIS for the rare (if ever) instance the RDS might go out. With regularly scheduled battery changes; it's even more unlikely. If stored in dark 1x per year is probably more than ample. If carried in open light probably more often.
However, in order to effectively practice the sight picture without RDS you would need to remove the battery on a Shield because they're normally on 24/7 with automatic ambient light adjustment but no shutoff. The RMS has a battery tray to remove battery without dismounting the optic so that makes it easy. The RMSc would require removal of optic to remove battery.

In either event, I really think you've got a great plan for your 75 Variants. Either Shield RMS or RMSc
provide an ultra low mount because they are small enough to mill in front of rear dovetail, hole pattern is narrow enough to eliminate the need for a mounting plate (unlike RMR); and in most cases can utilize the stock CZ front and rear sight for BUIS. Please keep us posted on your progress.

I'm waiting for my P-01 slide to come back from Primary with Shield RMS, Titanium Cerakote and stock CZ tritium BUIS I had installed last year. I love my P-07's with RDS; but I think I'll like my P-01 even better!!

I would also suggest you practice with a totally occluded optic window - tape over the window or something. 

Dot or no dot, you shouldn't take for granted that you can see through the optic.

I know with the RMR if I hold on a silhouette target where the top of the optic body cuts across the neck I get solid hits without needing to see through ;-)

Just when you think you've got it all figured out ...

Makes perfect sense ... I just hadn't thought about it ... thanks for the thought.

What would "occlude" a lens on a miniature red dot?  Cracked?  Yeah.  Knocked out?  Yeah.  But covered up??  Or if cracked, will it shatter like a hot marble dropped in a cup of cold water.  Cracked like ice, but still in the frame?

I have BUIS on my RMR equipped pistols (even though they are DI units and have no battery/electronics to fail) in case one gets so knocked out of whack that I'm not hitting what I aim it (thought chances are the BUIS would be knocked out of whack as well.

I'm still thinking about one of those shields for my new Omega P01, sooner or later.

[Vinny]

Mud or blood could occlude the lens.
It's Murphy's Law. Whatever Can happen; probably Will happen. 

I practice strong-hand only, weak hand only.
And there's a bunch of other scenarios that I should practice as well.
Point and shoot. Shooting from chest. Shooting at draw.

I remember my instructor having me shoot at 9 plates blindfolded. I thought he was crazy when he suggested it (no bullets thank you- just using electronic target verification). But, after a couple of tries to get my bearings; I hit 7 of 9 plates, blindfolded.

Practice builds confidence as well as muscle memory and skill.  All good things.

If you got knocked on your butt or dropped your pistol in the mud, it might be more expedient - critical, even - to get your hits and then clean off the gun.

Hopefully not something we ever see happen but... it could.
