LPA Mim versus Williams Notched sight

[jdub]

I just got an LPA Mim sight today from fellow forum member (thanks again!).  I thought I'd post a few comparison pics that show the size difference since I already have the Williams notched sight on a different pistol.

The LPA is on a 2240 and the Williams is on a 2300S.  In all the pics the HUGE sight is the Williams:












Some observations

The notch on the LPA is a bit wider than the Williams even though the sight blade itself is narrower.  (Note: adding actual measurements after the fact: The LPA notch is 0.117" wide while the Williams notch is 0.085" wide.  More of a difference than I thought.  The Williams notch width is very close the stock Crosman 13xx/22xx notch width of 0.075")

You can obviously see that the LPA has white dots.  Since I'll be using this for targets I'll black out the dots, which seem to work better for tactical type situations where you need to quickly acquire your target and fine control isn't has important.  In the case of most Crosman pistols unless you get an aftermarket front sight you have a plain black post anyway so the dots are of little use (for me--you may love them).

The Williams sight is much easier to adjust.  Fine adjustments are a breeze and there's a LOT more range of motion--both horizontally and vertically.  The LPA is not difficult to adjust but it's not as easy as the Williams.

Once you get them sighted in it all depends on your front post size and your preferences.  In my case I found the LPA and a nice wide front sight post to be every bit as accurate as the Williams.  In fact the notch on the LPA is better defined and not as shiny as the Williams.

For me the compact size of the LPA is a big advantage.  It's difficult the lay the 2300S down without it resting on the side of the sight and if it's bumped over or knocked around a bit the sight is going to get jarred.  The Williams also has to be set back far enough on the receiver so that you don't smack it with your finger when you pull the bolt handle back.  The LPA is out of the way.

I'm very happy with both sights but going forward I would probably get another LPA Mim before I'd get another Williams.  If the LPA becomes available again that is.  $40 for the LPA and $65 for the Williams.  You really can't go wrong with either.

Great write up.  I had wondered about those Williams sights.  IMO they lend a "German Luger" type of vibe to the guns.

I like my MIM sight, but the front blade looks so much smaller than the gap in the sight.  It makes me wish I could narrow it up a bit.  Certainly wouldn't want a wider front blade.

Thanks for the info.

Thanks for taking the time to post those pics Jdub, a pic is a 1000 words and all that

It's always a plus to have additional info.  Nice. RC

Thanks for the kind words!

You might want to reconsider a wider front sight.  Here are a couple more pics that might help to persuade you.  My 2240, the gun with the LPA installed, also has an LDC installed so the front sight is currently a 6-32 x 1/2" set screw.  The outside diameter (what you see when sighting) is 0.102" (sorry about the decimal places--not trying to be anal).  The stock blade sight on my 1322 is 0.104" wide (that's why I used the extra decimal places) or almost exactly the same width as the set screw.

However the rear sight notch on the stock 1322 is only 0.073" wide and on the LPA it's 0.117" wide.  So the LPA notch is over half-again as wide as the stock rear sight notch (almost 60% wider in fact) so it would make sense to widen up the front as well.

But here's my best argument for a wider front sight:






My IZH-46M has a rear sight notch width of 0.119" or almost identical to the LPA.  The Izzy front sight however is a very wide 0.145".  Now this is adjustable but this setup gives me a perfect sight picture with my very long arms.  Two nice clear, but narrow, white stripes on either side of the blade when aiming, but not too much white space, which can be problematic as well.

One other thing to consider is the distance from rear sight blade to front blade/post.  On the Izzy it's 12"--on my 2240 with LDC it's 16.5" so in theory the front blade on the 2240 could be even slightly wider than the Izzy.

One of my next projects will be figuring out how to get a wider front post on my 2240.  I have some hollow Delrin rod around here somewhere.  I might thread a piece for 6-32 and then turn it down on the lathe to the desired diameter.

Make 2

Make 2 

If I come up with something that isn't too lame to be shown in public I'll make several.

I just finished whippin-up 3 sights at work and drilling the TKO LDC with a .062 dia hole centered on the end cap. The sights are 308 SS and have a .06 dia x .31 long "pin" to go into the LDC, and the upper portion (the sight) is .128 dia. The pin side is the same for all 3 (to fit in the LDC) but the "fat sides" are .310 long, .375 long and .438 long respectively. I'll figure out tonight which one/height is best on the 2300KT with the MIM sight.

Man... I love this stuff!

Nice photos on both. I have an LPA right in my hand and my 1750 in the other and CANNOT figure out how the bugger is going to stay on. No instructions included but wrench and three-pronged flat-head screwdriver are all together. What am I missing? A part or a few brain cells?

Slide the sight into the dovetail slot and use the allen wrench in the 2 little holes which have set screws in them to tighten the sight to the gun

That is what I thought/figured but it just doesn't look like it would stay secure. Sooner or later I will try it on my cabin gun(s) but for now I don't want to mess with the scope and sight that is already on my 1750 that shoots perfect just as is.

While I have you guys, are there various versions of this sight? Maybe I got a goofy one? I'll try to provide pics later.

Thanks again, Jim!

I'll figure it out when I get there - so funny that I just can't imagine how it will stay in place.
