LeviSS Posted May 22, 2016 Share Posted May 22, 2016 (edited) I put the set of Dawson's from CGW on my SP-01. https://cajungunworks.com/product/ezd-9-40-for-9mm-and-40-sw/ I'm shooting 2.5-3"high at 20yds with 147gr loads. I've been putting up with it for a while, but I'm tired of having to adjust for it, so I'm looking for a new, taller front sight. I'm using the Dawson sight calculator to try to figure out what I need. I'm measuring the CGW front sight at 0.20" from the top of the slide. https://dawsonprecision.com/sight-calculator/ Does that sound right? Anyone have to put a taller sight on with this set? - Edited May 23, 2016 by LeviSS Link to comment Share on other sites More sharing options...
bthoefer Posted May 23, 2016 Share Posted May 23, 2016 The front sight of the CGW set is a .195 tall Dawson. I'd try the .215 for 147 grain loads. The .205 is what I'm using for 135 grain loads. Link to comment Share on other sites More sharing options...
brian45acp Posted May 23, 2016 Share Posted May 23, 2016 The cgw sights are perfect for 124grn on my 75 compact and sp-01. 147 seems to always be an issue. I bet Cajun guys can take care of you and get a taller front of you call in Link to comment Share on other sites More sharing options...
GJGary Posted May 23, 2016 Share Posted May 23, 2016 147gr always shoot higher, the slower bullet stays in the barrel longer so it is picking up the muzzle rise ever so slightly causing it to shoot higher. I have at least 5 different height fron sights for the different bullets and powders I have played with. Link to comment Share on other sites More sharing options...
tha1000 Posted May 24, 2016 Share Posted May 24, 2016 I have the same issue with mine. I'm planning a switch to 125's when I shoot through the last 4k 147's I have.. Link to comment Share on other sites More sharing options...
Hallz Posted May 24, 2016 Share Posted May 24, 2016 Funny, I have the same issue with 147 hitting high and 124 POA/POI,.... What is strange is I tried some 145's and they are POA/POI as well. I tried 147 plated and coated and they are all about 2" high as well. Link to comment Share on other sites More sharing options...
bowenbuilt Posted May 24, 2016 Share Posted May 24, 2016 Most of the ones I have installed have a .170" tall front sight (as advertised) measured from the top of the slide. So far I have replaced them with a .185" tall front for 147's and it has worked out perfect. Depending on the depth of the front sight dove tail your mileage may vary.

Moltke Posted May 25, 2016 Share Posted May 25, 2016 Why not just get adjustable sights and zero the gun for point of aim at your desired distance Link to comment Share on other sites More sharing options...
bthoefer Posted May 25, 2016 Share Posted May 25, 2016 Why not just get adjustable sights and zero the gun for point of aim at your desired distance Because getting the slide machined for LPA sights is a pain, and I'm not thrilled about the available lpa sights. Also adjustables will break. Fixed sights are harder to get a perfect zero for, but once you are happy they are basically permanent. Dawson precision will make custom sizes for $10, I'm the guy who paid to get a .205 tall by .090 wide sight built. The real advantage of adjustables is if you change loads often.

Moltke Posted May 25, 2016 Share Posted May 25, 2016 This wouldn't work? http://czcustom.com/cz-parts-all/front-and-rear-sights/rear-sights/sp01-shadow-75-shadow-rear-sights/zdl-shadow-adjust-rear-sight.html "Shadow Adjustable Rear SightFits the SP01 Shadow and 75 Shadow rear sight dovetail. Adjustable for windage and elevation. This is an UPGRADED version of the sight sold on the CZ UB web site.We contracted with the manufacturer to be the supplier for the USA and has Several Substantial change made to this sight.We added set screw, different elevation screw and a stronger more reliable pivot pin. This is the same sight we use on the SP01 Shadow 2 as sold by CZ USA distributors.Requires a 7.5mm Front sight." Personally I've never liked the sight height guessing game so I just get an adjustable rear, zero, and move on - but hey, as long as you're zeroed!

LeviSS Posted May 26, 2016 Author Share Posted May 26, 2016 Thanks guys. I ordered a .215 front sight and got it put on today. It's hitting exactly where it should now. That should help. Link to comment Share on other sites More sharing options...
