Thanks to CZ85Combat and Wobbly. This was helpful. ZZ

Yes I have heard of it but I am not certain what sound I am listening for and it is for that very reason that I am looking at a more empirical way to establish an optimum OAL. I have reloaded with jacketed projectiles for many years but now I am switching to 9mm LRN bullets for range use and they seem to require an OAL in the vicinity of 1.090" to keep the ogive off the lands and a far cry from the OAL I am used to for jacketed bullets, 1.125" to 1.130". I can see a full blown charge ladder on the horizon. The gun is a G17 with a Storm Lake barrel. Bullets are 115 Gr LRN from Oregon Trail. ZZ

Thank you much, ZackJones! ZZ

On another forum a member said that he found a reliable method to determine the maximum OAL for a specific bullet and barrel by using a dowel as a measurement tool. He said that he found it on one of the BE forums. Can anyone steer me toward this thread. I am unable to locate it with the search tool. Many thanks, ZZ

Perhaps the muzzle flash, being more visible at dusk is your "flashbulb". This would cause a bright, instantaneous sight picture and a possible after image as well. ZZ

I received my new DP adjustable rear and after seeing how thick the notch sides are (front to back) and upon further reflection, I decided not to attempt the modification. I coupled it with a DP .285x .100 FO front and after 100 rounds, I'm warming up to the .125 notch. (I have been using the stock Glock notch up until now) I plan to use this sight for a while and will re-evaluate it in the future. This process of selecting the best sight combination for me is a bit like finding the "best" carry holster. I have one that I love but I also have a drawer full of 'em! Thanks to all for the very fine input. ZZ

I am not new to shooting but I am developing interests in competition for the first time. I'm not clear on the meaning of the terms indexing and natural point of aim. I would appreciate definitions of the terms and I am wondering if they are they related in any way. Thank you in advance, ZZ

While reading this thread, I ran across the sentence..."Natural Point of Aim...not to be confused with Index." I think that I am doing just that. Would someone please define the terms index and NPA for a noob. Thanks ZZ

Are there any thoughts about the Slant Pro rear vs the Straight Eight rear for a G17? ZZ

Rats! Stician is correct. They said no. ZZ

Sorry for being late to the party with this suggestion. Maybe it will help others. Hold your sights on target using your normal stance and grip. Have someone measure the distance from your sighting eye to the rear of the front sight. Take that number to your optometrist and ask him to make bifocal lenses such that the top is focused for the front sight and the bottom is focused for your normal reading distance. If the focal distance of the top lens falls between two available values, opt for the longer focal distance. Ask to have the bifocal line set 2mm lower than usual. This will assure it is out of the way but it will still be useful for seeing detail at near. Now what you have are bifocals that will snap the FS into focus immediately. The rear sight will be a bit out of focus, (the greater the sight radius, the blurrier the RS will be) and the target will also be somewhat blurred. Full disclosure...if you are shooting long precision shots, this plan will NOT work due to target blur. I know this works because in an earlier life, I was an optometrist and have prescribed many of these for older shooters. In fact I would have them bring the weapon into the office for the measurement. This may be unacceptable these days. ZZ

That's good to know. I have not asked the good folks at DP yet but now I am wondering if they will do the filing for me. Maybe I can get a 0.150" notch after all. ZZ

Thanks to all for the great suggestions. I like my current cheapo Bladetech (except for the sight channel) so I plan to upgrade to the standard model tout suite.

I guess the subject line says it all. I would prefer a 0,145" to 0.150" wide notch instead of the 0.125". Has anyone defiled (sorry) a Dawson adjustable rear in such a way? I have never looked closely enough at one so I don't know if it is even possible to open it that much. It's curious to me at least that a wider notch is not offered for the "old eyes" etc.

I am told that if the velocity is below 1100 fps, shooting lead in a Glock barrel is not a problem. But, my advice is just don't do it.

Okay. I researched the Bladetech holster that I have and as I said earlier, it is the cheaper "Revolution" model. Their standard model might have a larger sight channel so I wonder if anyone has had experience with the standard Bladetech G17 holster and a 0,300" FS height? zzulu

Neither actually. Primarily I will use this gun at the range to improve my shooting skills but there may be some Steel Challenge around the corner. I have a Bladetech holster (there are two and I have the cheap one) and the sight channel is a bit small for the 0.300" FS. Perhaps the more expensive Bladetech has a larger sight channel. I will definitely look at that possibility. Thank you for the advice. zzulu

I would like to mount a DP adjustable rear sight on my G17 but the height of the front sight, (0.285" to 0.300", is so great that it will not work with any of my current holsters. I would appreciate any suggestions. Can anyone suggest Kydex OWB holster with enough clearance for this rather tall FS? zzulu
