Noticed Lancer started selling SP500 .22 break barrel pistols on Amazon for $47 shipped, goal is to have dartboard pistols.

Ordered two. Both barrels tilt to the right but was able to move rear sight mount to compensate and keep sight centered and it might be getting better with breakin. Finish is great, small gap in top rear trim around spring endcap, grip trim fit is perfect.

Theres no m3x10mm grubscrew trigger hole for pretravel adjustment, they removed it from this variant. If someone can help on angle and position the hole is itd be appreciated.

The sear engagement screw seems to be maxed out already at the point just before slamfire on hard barrel closing. There was no point in filing down the screw so it could fit past the hardstop, why is this different?
 
i have no idea why they change but without the trigger work this are junk

2.5mm drill and i would start with a 2mm and i would also tap it vs just using the screw

10mm grub is too long, maybe 5mm. Difference is subtle to me but big to Geezer, probably need to just remove trigger spring before it's useful to add grub screw although it removes pretravel. Geezer drilled hole with finger drill using 2mm drill and hole in trigger guard as a guide, IMO it was too small a drill bit since it took 30 minutes to get it tapped.

Consider adding loctite to barrel pivot screw.

Since the sear is rounded off the easiest thing is prolly to just remove trigger spring. For a hair trigger you really need to un-round the sear. Having the added grubscrew 1/8 turn away from slamfire didnt feel much diff than stock IMO aside from pretravel, no hair trigger with just grubscrew.

Shame these went from $47 to $58 in a month.

Easy hair trigger upgrade, remove trigger spring, thats all! Adjust the existing highlighted screw inwards to further reduce trigger pull.

theres no reason to tap and add a grubscrew to the trigger unless you want to adjust without taking case off.

Be sure to smack it around a bunch to test for slamfires. Add loctite to this screw and the barrel pivot nut.

i concur the trigger spring is not needed the sear will reset the trigger and if you install the screw and lower the sear screw the trigger is first rate and that will give anyone looking for a nice little spring pistol something to buy
now my pistols had been done already and the spring removal was icing on the cake
great idea
now the trigger hole is 5.5mm and the pin is 5mm and the case and cover hole are more then 5mm so that could be a place for a larger pin and it could be shimmed but 0.5mm was too much, i think .1mm each side .2mm total could help
i put some tape in the frame hole and that helped
great idea thank you
