Non-stationary pierce gun

Just an observation, gunslingers do not have access to a piercing gun that they can use while moving
the callahan is great (i have one) its almost as powerful as a rigadoon per shot - which is fantastic, but it locks u in place while firing, not a huge problem to fire a single shot, except against T3 wolvers.
the needle lines, plague and blitz are considerably worse, your locked in position while firing a spread of 6/7 shots, more than long enough for a devilite to quickstep out of range and throw office furniture
I also noticed that most of the gear kozma sells can be upgraded along different alchemy paths,
calibur ->cold iron
defender -> heater
cobalt armor -> vitasuit (kinda)
blast bomb -> all other non chemical bombs
all thats missing is a blaster variation and helm variation
so my idea is create a piercing blaster variant, starting at 3/4*
that way the blaster may see more action and theres a piercing gun that you can run and gun with.
so far as new models are concerned, i dont think any are necessary, just reskin the blaster line with different colours.
I know that there is the antigua series, but they are not pure pierce and as such cant really be considered to be piercing weapons. they're great, i love my peacemaker but its just not a real pierce gun.
PS im also of the opinion that there should be another version of the antigua which deals shadow and elemental, round off the series will all split damage types - though a revolver being useful against constructs and slimes, seems a little odd

honestly so would i, full piercing 5* antigua would be great, but i thought that this approach would be a more accessible solution, and it combines two of my thoughts into a single suggestion

The Heater Shield and Vitasuit Deluxe branching from the Spiral Order gear were toss-ins; due to certain items starting off at high star-ratings, one could get their self T3-ranked equips just by finding the respective recipes and crafting them, or simply finding someone else who could craft it.
Thusly, item lines that started at higher star-ratings and had no rarity factor were added to existing item lines, reasonably.
How about a Full piercing Antigua line?
Possible names:
Hypervelocity
Mach stream
Pointmark
Any others?
But i dont use antiguas because of theese stupid wings it has on more than 3* and color( Dark purple and golden r not my fav u know...) But 3* version is fully OK for me...And it matces most sets ingame coz its grey. Maybe instead of wings there should be added more barrels (but it will look similar to Cerberus gun....or blue rose...)
Drill gun----> Turbo drill gun ----> Triplescrew!!!! lol im just kiddin... The 5*s name could be *Penetrator*. Tats all
I would be happy with a fully piercing 4*-5* version of Antigua actually. :D
EDIT:
the needle lines, plague and blitz are considerably worse, your locked in position while firing a spread of 6/7 shots, more than long enough for a devilite to quickstep out of range and throw office furniture
Tsk. Don't knock it until you try it. You will learn how to use it and be a believer too, like me.
Just don't use the normal attack. :D
