Yes it fits perfectly. You can adjust the paddles and the position it sits on the rail
ABSOLUTELY! I have one installed on my X Maxcro Tacops.
So the short version as long as you have the macro frame yes it will fit. Though be advised this is more the size of a TLR1 & on most macro frames it's going to stick out like the x300 does on a lot of full size which for some people they like as it prevents slide being pushed out of battery but I personally don't let people get that close! Though I personally would recommend & personally use a Foxtrot-1 on a Sharps Bro's Macro Frame as more compact. But I kept this & actually swapped out a TLR1 on a different one. I don't know how knowledgeable you are about lights the lumens are neat to know Candela is just as if not more important. So the FT1 is 450LM 12K Can compared to a TLR7 500LM 5K Can the beam patterns on both FT 1&2 great hotspot with great spill but one you can't beat the price & it comes with rechargeable usb-c battery(2 if I remember correctly but only needs 1 do get a bu)& multi pos rail adapter so you can adjust the light the only thing that I don't like about the FT1 is the switches(stiff for like 1-2mons) the FT2 has SL TLR paddle switch(you get 6 diff sizes you can swap out to your preference). I used to have mindset if work was paying, it was normally SF,Cloud(expensive ones)lights if I'm paying its SL & watched a review on lights & where I learned about Candela helps punch through photonic barriers like window tint (but there are some which might be great but I don't have trust or level info with SF&SL like OL I may use it on a home pew but I have used SF/SL professionally for 20+yrs & put my life on line so just a personal thing but the Sig has changed my mind like inforce rifle lights) The FT1 blows my TLR7 out of the water like I may have 5% tint & clearly see through it as it's 2x the Candela. I was so impressed with the FT WML's I was taking a class at Sig & ended up buying a handheld light originally was going to be a backup light but often use it as primary if a vehicle has tinted windows & actually bought the compact one for EDC. I liked the cost(discounted)it came with 2 rechargeable batteries(how many companies give you a b/u) but biggest is 1 setting bright AF & 3 modes off, momentary, constant vs light I used to have on my shoulder epaulette had like admin,Low,Med,High,Turb. For a primary I want it on & no question what mode it's in(brightness settings). Lastly if you go to Sigs website they have multiple pics under reviews of the FT2 on a Macro & you can see it's not flush with the barrel as the FT1 is
