"When opportunity knocks!!!"

I did a calculation the old fashioned way and got a nominal 0.225" at 25yds, then tried the 50 yds, got double that as one might think. 4 inch barrel, with 0.001" offset. This only has the barrel length and not the barrel length plus action length to rear sight.........ie sight radius, which as most knows, varies with model.

I then tried the parameters in this Brownell's software set, no familiarization with this piece of software; first time to try it.

G.T. is going to put out some bucks for this, just wanting to make sure he got the right stuff. Only asking someone mathematical to double check.........if I am wrong, I am sorry; but my home brew approach and the software above agree. Plug in the numbers and see if you agree or not.

I have no dog in the fight on what to offer as to sight heights. Only inquiring about the theoretical calculation. I have moved on to adjustable rear sights and even scope bases on my Lugers now.

Someone will appreciate the availability of front sights again, I am sure. The old Marble's 27 was a nice sight for some applications, but not produced for a while now.

My best to G.T.'s offering.
