CHLChris Posted November 9, 2013 Share Posted November 9, 2013 Hey! I'm using Sevigny FO competition sights on my Glock 35. The POI is a few inches (3" or so) lower than my POA, even at at 25 yards. Even though they suggest the .245", should I go with the .215" front sight or would that make too big of a difference? I know Dawson makes some FO front sights at different heights.

DDirks Posted November 9, 2013 Share Posted November 9, 2013 Are you using the Sevigny rear sight as well? Link to comment Share on other sites More sharing options...
JBP55 Posted November 9, 2013 Share Posted November 9, 2013 Going from the .245 front sight to the .215 front sight on a G35 should raise your POI approximately 3.5" at 25 yards. Link to comment Share on other sites More sharing options...
enutees Posted November 9, 2013 Share Posted November 9, 2013 I just had the exact opposite problem and switched them. I'll trade you a .215 for your .245. Link to comment Share on other sites More sharing options...
CHLChris Posted November 9, 2013 Author Share Posted November 9, 2013 enutees...just PM'ed you! Yep, matched set from CPWSA: Sevigny Competition front and rear. 3.5" raise on POI might be perfect! Link to comment Share on other sites More sharing options...
dsmw5142 Posted November 9, 2013 Share Posted November 9, 2013 I always use a .235 from Dawson Link to comment Share on other sites More sharing options...
45 Raven Posted November 9, 2013 Share Posted November 9, 2013 Dawson Precision's website contains a simple formula for calculating what you need for a front sight height if you already know your current sight height and point of impact. Link to comment Share on other sites More sharing options...
CHLChris Posted November 9, 2013 Author Share Posted November 9, 2013 So, I could use math? How about getting 4 different sights and spending $50 on ammo and range time? Hmmm.... I'll choose math. Or, take up enutees on his offer and cross my fingers! Link to comment Share on other sites More sharing options...
Cardinal Posted November 9, 2013 Share Posted November 9, 2013 For Glocks, take a look at this site to calculate sight height: http://www.ameriglo.net/sights/calculator Link to comment Share on other sites More sharing options...
leas327 Posted November 9, 2013 Share Posted November 9, 2013 I have a 35 and had the same problem with the sevigny rear and a .245 front. The .215 was better. Link to comment Share on other sites More sharing options...
dlouie87 Posted November 10, 2013 Share Posted November 10, 2013 Mine is shooting low too. I'm looking for a .230 front but if any of you folks would like to trade a .215 for a .245, I'm willing to. Link to comment Share on other sites More sharing options...
CHLChris Posted November 11, 2013 Author Share Posted November 11, 2013 Is yours only shooting an inch too low? Just for the record, part of the issue here is that my competition load is the Atlanta Arms 170PF. When I'm shooting factory loads, the POI is only, maybe, an inch low at 25 yards. I really prefer 6 o'clock hold anyway. Link to comment Share on other sites More sharing options...

I really prefer 6 o'clock hold anyway. It's around 2-2.5'' at 25 yards. I'm shooting walmart 115gr. Do you think with reloads and with a 124gr bullet, the poi will come up a few inches?

JBP55 Posted November 11, 2013 Share Posted November 11, 2013 Going from a 115gr. to a 124gr. will raise the POI slightly but not 2.5" at 25 yards. Link to comment Share on other sites More sharing options...
CHLChris Posted November 12, 2013 Author Share Posted November 12, 2013 Not to go far afield, but I've noticed in rifle bullets at 100 yards, that a "reduced recoil" 125gr 30-30 will impact just about an 1.5" lower than full-power 150gr load. In that case, we're talking a whole 100 yards and we're talking about a much bigger difference in power between the two loads. Though I don't know about 9mm concerning POI changes between loads, I can't imagine any more than an inch difference at 25 yards. Changing the front sight would be a bigger difference than changing loads, it seems to me. Link to comment Share on other sites More sharing options...

CHLChris Posted November 12, 2013 Author Share Posted November 12, 2013 Are you asking me, the original poster? I prefer 6 o'clock hold, but my current front sight (currently in the mail on its way to enutees, by the way) forced me to maintain center hold or even 12 o'clock hold. Not my cup of tea...

Jadeslade Posted November 12, 2013 Share Posted November 12, 2013 Yes. Link to comment Share on other sites More sharing options...
Jadeslade Posted November 12, 2013 Share Posted November 12, 2013 Sight picture is the relationship of rear notch to front sight. 6 hold is a point of aim. Link to comment Share on other sites More sharing options...
CHLChris Posted November 12, 2013 Author Share Posted November 12, 2013 Then I don't understand your question. To me the answer is so obvious that it is as if you were asking me in which direction do I insert the magazines? The front sight is centered in the rear slot and the black tops of the front and rear sights are aligned straight across, thus the point of the fiber optic light tube is just slightly below this level. What else would you expect? I'm not going to get used to a different sight picture. It is much easier to change front sights, yes? Link to comment Share on other sites More sharing options...

Jadeslade Posted November 12, 2013 Share Posted November 12, 2013 Then you don't need the fiberoptic, do you? Link to comment Share on other sites More sharing options...
CHLChris Posted November 13, 2013 Author Share Posted November 13, 2013 What does that have to with it? Are you thinking the fiber optic dot should be even with my rear sight? Yes, I agree that would bring up the POI, but it also isn't the best way to fix this issue. Seems to me that the FO is a great way to draw the eye quickly to the front sight, but one still has to align the top of the front sight with the top(s) of the rear sight. You're obviously very experienced, Jadeslade, so I'm not the one to argue with you. If you've got some insight, do tell, but your Socratic method is wearisome.

S&W686 Posted November 16, 2013 Share Posted November 16, 2013 On my Glock 34 and 35 I have Warren Tactical Sevigny Rear and .215 Dawson Fiber Optic Front and this combination has worked very well for my. Link to comment Share on other sites More sharing options...
dravz Posted November 17, 2013 Share Posted November 17, 2013 I have the .215 on my 34 and 35 and I like the POI with this setup way better than .245. Link to comment Share on other sites More sharing options...
