Can anyone tell me the model# for j frame with interchangeable front sight?

[jringo8769]

Well sadly as my eyes are getting worse than ever...i find myself dealing with some serious health issues and i find myself wearing shorts all the time now due to being so hot no matter what is happening outside...i want to get a small j frame for my pocket again and the one i was using i find it very hard to see the front sight...but i also carry a Glock g27 with night sights and i can just see the front sight so it got me thinking about a j frame with the tridium front sight and my search started...but i can not find any way to search which ones will have this...i would prefer a hammer gun like a 37 but i am not opposed to a 340 or one like that...i just need to be able to put that larger front sight on it...i have been looking at the 360 pd's which are very nice...but around here they are crazy money..i am hoping this will not add insult to injury...i really like the idea of the 357 too...any help with this will so be appreciated...thanks in advance God Bless,John

here is the ones i think have this interchangeable front sight
1..340PD
2..340M&P
3..360M&P
4..360J

I have a 340PD and a 649. The 340pd weighs just over 11 ounces and works great for summer carry in my shorts pocket. The 649 is all stainless. Both are 357/38. The front sights on both of these are pinned and can be changed. I have XS Big Dots on both. Works for me!

Model 640 Pro has some updated sights. Not sure about a normal ole 640.
